Messy Chestnut: "Start a fast food restaurant called 'Whoops!' Have the #1 on the menu be the 'Big Whoop' (with cheese, etc). Then never actually have them so that when people come up to the counter and say, 'I'll have the #1' you can say 'no Big Whoop.' It's critical that the server says this with no expression and without moving their lips. I think there's a lot of money in this idea, but my wife doesn't think so."
