Mike and Frank are out in the Kentucky on a different kind of mission. They're going to someone who needs their expertise to make his home unique. The owner is William Shatner, who gives Mike and Frank a very specific list. While Danielle looks for leads, the picking is red hot at Thurman's Tennessee hills property. The lifetime collector says he's ready to make a deal, but is he really? Next, the guys hunt for the perfect showpiece for Shatner's garden and think they've hit the jackpot with an amazing millstone collector. That is, until they find out his prices outweigh even the heaviest of stones. And, with just one week to deliver the goods to their celebrity client, Mike and Frank call in a favor from a designer friend. Finally, with a van full of treasures, they deliver their booty to Shatner, hoping they haven't let him down.

With a gleaming airstream trailer in tow and a buyer lined up, Mike and Frank hit the road to California. When the deal falls through, they find themselves in hot water until a rare opportunity leads to an awesome trade. Like a Hollywood back lot, Guy's jaw-dropping collection includes an entire village built from scratch. It's the pick of a lifetime where every building is packed with classic cars and vintage movie memorabilia. Mike and Frank get first crack at a lifetime collection that includes the biggest collection of leather aviator helmets they've ever seen.

The guys pick a Pennsylvania warehouse and find a rare comic book that gets Mike's "spidey" senses twitching. Frank tries to negotiate for a vintage cigarette machine with a lifetime collector who is also a reluctant seller. A ramshackle old house in South Carolina looks promising but it's also said to be haunted by a ghost named Pearl.

With Frank too sick to go picking, Mike's brother Robbie scrambles to fill in at the last minute for the trip. In Idaho, the guys find a barn-sized man cave filled with an awesome collection of Western Americana including antique spurs that could be worth huge money. In Oregon, with a serious wager on the line, Robbie feels the pressure to out pick Mike and scours for a big-ticket item.

These giant mountain-sized boulders from space have wrought death and destruction throughout the millennia but until recently geologists could find no evidence that they had actually struck the earth. Follow the remarkable detective story that begins at Meteor Crater in Arizona as mining engineers desperately try to unearth the billion dollar iron boulder they thought was lying there. It's a detective story that also uncovers immense riches; the world's biggest nickel deposit in Sudbury, Canada, vast oil reserves in the Gulf of Mexico and a gold mine in South Africa--all the result of asteroid impacts. Evidence is also unearthed of violent impacts that decimated some of the first people to live in America. What clues do asteroids, and their smaller cousins, meteorites, hold in the formation of the early Earth and perhaps life itself?

Many scientists now believe that a "killer asteroid" wiped out the dinosaurs and 70% of all living things 160-million years ago. How likely is it that a similar event can occur again? In this episode, we explore the catastrophic effects of a 2-kilometer-long asteroid hitting just off the coast of Los Angeles. Using the Chicxulub asteroid impact of 160-million years ago (the one that killed off the dinosaurs), we watch--moment by moment--as the blast annihilates not just Los Angeles, but communities within 100 miles of the coast. A firestorm consumes much of southern California and tsunamis wreak havoc up and down the entire western US coast. The resultant dust cloud covers much of the Midwest, devastating crops for at least a year. Millions of people die from the direct effects of the impact, and millions suffer a famine the likes of which the world has never seen. The good news is that technology has given us the tools to--perhaps--avert such a disaster.

What are the latest discoveries in the deadly world of asteroids? Will a recently returned Japanese spacecraft become the first to bring an asteroid sample back to our planet? What would happen to America's East Coast if the massive asteroid impact that helped form Chesapeake Bay 35 million years ago struck today? And why did President Barack Obama choose an asteroid as the destination for the next great manned mission into space? Learning about these huge space rocks isn't just about science, it's about survival.

It sounds like a Hollywood blockbuster: a deadly asteroid is on a collision course with Earth. But in reality, it's only a matter of time before a giant space rock threatens to wipe out civilization. An asteroid took out the dinosaurs sixty-five million years ago. Are we next? This episode analyzes the threat and explores the many ways--from a nuclear bomb to ingenious new technology--that experts are proposing to stop Armageddon.

Asteroids, comets, gamma ray bursts and the sun all combine to make the Earth a dangerous place to live. NASA's top brass and other scientists are arming themselves with the latest technology to pre-empt an apocalyptic attack. Watch and investigate bizarre, and terrifying apocalyptic scenarios and the ways that scientists are racing against the clock to develop technology to defend our planet.

It's been said that our universe is a cosmic shooting gallery. Gravity is moving everything around and things are bound to collide. Astronomers are attempting to understand how these collisions occur in the dark recesses of space. Learn about collisional families, which are clusters of comets and asteroids; planetary collisions; mass extinction impacts involving asteroids and comets; stars collisions; and galaxy cluster collisions. Cutting-edge computer graphics are used to bring this series down to earth as the heavens yield their greatest secrets.

As the last day of the month-long alligator season dawns, the moment of truth arrives. Today is about one thing: tagging out before the season ends at sundown. Troy is determined to hold on to his crown. He s got only 14 tags to go, but to cement his reputation Troy wants one more monster gator...one that will make a statement to the competition. R.J. and his son Jay are down to their final tags. For this father-son duo, tagging out will mean that they ve filled a bayou-best 500 tags this season. Bruce, Ron and Tyler are facing a daunting final day. The elements have wreaked havoc on Bruce s territory all season, and after Lake Pontchartrain overflowed during a storm, brackish water has chased most gators from the area. With so few tags left, Liz and Kristi are determined to finish fast, but soon, the mood sours. A fish kill from dropping oxygen levels in the water poisons the honey hole, and with so many dead fish around, gators aren t biting.

After a hurricane tears through the bayou on opening day of Alligator Season, delaying hunting for five critical days, the swampers turn to family to help make up for lost time. Complicating matters is the arrival of two new hunters who invade the Louisiana swamp from their native Texas and challenge King of the Swamp Troy Landry to a high stakes bet. The shortened season forces everyone to take bigger risks including one hunter who jumps into the water to wrestle a huge live gator that tries to get away.

In Ohio, Truck Hunters Shawn and Vince must track down and deliver a big rig filled with highly classified cargo but mid-route they pick up a mysterious tail. In Texas, a trailer filled with prized cattle is stranded on a track, and Marshall and Korchenko is the trucker's last hope to avert a disastrous collision. In New Jersey, brothers-in-law John and Gene are on the hunt for a hijacked truck full of a million dollars worth of laptops. And in Denver, Animal and Steve discover the perils of trying to deliver a hot load on a tight deadline, as the President's visit locks down the city's traffic grid.

Run for cover with the Pawn Stars when a World War I helmet blasts into the shop. The first metal helmet used by U.S. forces, will the guys butt heads to buy this piece or will they dig in for a long negotiation? Then, Corey and Rick are presented with a gun holster used on the long running TV show Gunsmoke. Will they round up a posse and go after this prop with guns blazing or are they just blowing smoke? And later, Rick decides the guys could use some exercise and hires them a personal trainer. Can he convince these couch potatoes to "feel the burn" or will they decide there's no gain to pain?

It's a high stakes proposition when a man saddles up to the shop with a 19th century professional gambling set. Complete with knife and pistol for when the going gets rough, will Rick go all-in to buy this rare piece, or will a suspicious marking make him call the seller's bluff? Then, a man bops in with the doll version of Chumlee's favorite rapper, Snoop Dogg. Will Chumlee scratch up a platinum deal for this collectable piece, or will the negotiations go up in smoke? And later, all bets are off when the guys have an after hours back room poker game. Will the Old Man live up to his King of Cards claim, or will one of the guys make him look like a joker?

They lit the path to a brave new world and led the way to safe harbors as they warned of dangerous coastlines. They welcomed ships carrying precious cargo and new citizens to the fledgling country. But today, many American lighthouses face grave danger. While heroic efforts by concerned preservation groups and local governments have saved some, many are perilously close to being lost forever. Host Josh Binswanger looks at efforts to protect these beautiful and historic American treasures.

Meteors, comets, and asteroids cross the solar system to offer clues about our planet and universe. Can they destroy civilizations? Did they wipe out the dinosaurs? Have they brought life to our planet? And when will the next one hit? Aided by elaborate animation and live-action footage, we learn what these mysterious space rocks really are and imagine what likely happened 65-million years ago, when an object plowed into the Yucatan Peninsula. We see how certain spectacular meteor falls advanced our understanding of what they are and the danger that they pose. We talk to leading experts--astronomers and geologists including David Levy and Carolyn Shoemaker, co-discoverers of the Shoemaker-Levy comet that fell into Jupiter in 1994. And we talk to NASA scientists about recent missions to asteroids and comets and speculate on ways to move Earth-threatening asteroids and comets out of our way. Because it isn't a question of if but when the next deadly impact will take place.
