If you don't know what a "Castanza Wallet" is, you must have missed the 90's. In one Seinfeld episode, Jerry makes fun of George because his wallet is thicker than the sandwich he is paying for. George claims that he needs everything in his wallet and it's about 3 inches thick. I have been accused of having a Castanza wallet as recently as this weekend. For some reason I put every receipt, business card, and other random small pieces of paper I end up with into my wallet. The sad thing is that there's no cash in it at the moment! Am I the only one here with a Castanza wallet? Come on, don't be bashful!
