A spotlight on Stewart Berkowitz and his collection of costumes from TV shows.

"Monster Party" podcaster Shawn Sheridan is into horror, his wife Gina is all about sci-fi. Together they've made their pop-culture passion a cornerstone of their marriage, as we find out when Lisa joins them in the room they've dedicated to their shared collection of action figures, memorabilia, and more. Shawn and Gina display such treasures as "Galaxy Quest" glasses made exclusively for the cult TV show's crew, and full-size replicas of both the killer doll from "Trilogy of Terror" and Twiki the robot from TV's "Buck Rogers" (who actually talks and shares a few choice words). Lisa brings along toy collector and creator Gavin Hignight, who will put a value on Shawn and Gina's entire collection. But things really get wild when Gavin calls in "Collector's Call" all-stars (and Shawn's co-podcasters) Matt Weinhold and Larry Strothe, for our very first double trade scene!

Kenneth Guinup's love for "Weird Al" Yankovic goes back to his childhood, when Al's response to his fan letter helped Kenneth through a difficult time. Now Kenneth isn't just a lifelong fan, he's a collector who's assembled a wild and wonderful range of "Weird Al" artifacts, collectibles, and one-of-a-kind treasures, including Al's very first EP, an exclusive jacket given only to "Weird Al's" video team, and a screen-used guitar signed by the entire band. Lisa's brought along Jon "Bermuda" Schwartz, who in addition to being "Weird Al's" drummer is also the band's archivist. Jon will place a value on Kenneth's entire collection, then try to tempt him into a trade for not one, not two, but several irresistible inside-the-band items. And in a special surprise for Kenneth, "Weird Al" himself beams in for a shout-out , and to pass along a very special, very personal gift.

You might be hard-pressed to find anyone who loves pizza more than Telina, not necessarily eating it, but collecting pizza related items. Telina found her passion when she was traveling around the world and noticed how everyone, everywhere, can get behind PIZZA. Today the Guinness World Record holder shows off for some of her most offbeat, and some might say, cheesiest pizza items. There's her pizza swag chain, and pizza box from a cult classic movie, not to mention her pizza dress, designed especially for her. Joining us today is John, best known for his toy expertise, but being Italian, and loving pizza, doesn't hurt. After valuating her collection, John will present Telina a trade offer that'll be incredibly hard to top.

There are Star Wars collections, and then there is Gus Lopez's out-of-this-world, Star Wars collection. A fan of the space opera since he was a kid, Gus doesn't just collect the obvious, Han Solo's screen-used jacket, one-of-a-kind prototypes, C-3PO's body parts, but there's also the ultimate weapon, you know the one, THE DEATH STAR! So with a collection like that, we had to call Rob Klein, an archivist, pop culture expert and huge Star Wars fan himself, to walk Lisa through this incredible collection and try putting a value on all of Gus's prized possessions. Then, Rob attempts to make a trade with Gus, by bringing him a special Star Wars collectible that may not be familiar to every Star Wars fan, but in exchange, our expert wants something that reminds him of some quality time he and his Dad shared a long time ago.
