I would like to think that Chumlee is an actor because he's a pretty large waste of good oxygen otherwise. Sheesh!
What i don't really understand about this show, considering that most people are selling with no intention of returning to claim a piece, is why they don't just sell the stuff on ebay. These guys only offer them a third of the value at best. If they needed a quick sale i might understand, but in order to get this stuff set up time must be involved, so they could probably get more money on ebay in the same time.
