One of my cow-orkers is known for taking stupid bets. Someone bet him he couldn't keep one of those mega breath mints (I forget the brand) up his nose for a full minute.
We have it on tape.
The most amazing part was after he finally blew the mint out. You could smell the mint on his breath 10 feet away from him. Something to do with the interaction with the mucus, I guess, but man, his breath just about knocked us over.
