Phat Wad, Break me off some
The biggest representation of $200. (Well, $198 now, since I bought myself a $2 tuna fish sandwich). This started as a joke by a friend of mine where he suggested to pay for something with a stack of ones with a big bill wrapped on the outside. I thought it was a great idea, and since our vending machines in office only take 1's, I got a hundred of them and wrapped them in a single $100 bill.
