Didn't expect the bastard to be you, Cheebs. lol
I love having friends like that, one of which was always the butt of our pranks in my group of friends during high school days. There was one time we took her ketchup packets when she looked away, and thinking she forgot ketchup, she went back to the line in the cafeteria for more. And when she got back we took something else and the cycle repeated. After a few times I put the ketchup back and she was so pissed off she blew up and threw the packets at me.
