My buddy was in vegas last week for an HP conference, he went into the store and was talking to the 400lb black guy who you see in the background as the bouncer. He said that guy is absolutely huge, but they shut down the store for filming the episodes otherwise it's like 300 people in this tiny place constantly. He didn't see Rick and the gang as those guy are probably in the back room counting their money.
There is another similar show called Pawn Queens, best part is these two chicks and the tight t-shirts they wear. But one of them is ruthless bargainer..

can't say i'd throw either one of them out of bed for eating crackers....then again thats not saying much
