Whatever you do, just don't pull a Richard Gere.

I find no humor in any of these vile statements.

Put him in a sandwich bag and place it in your jacket pocket. then go to an expensive resturant and order whatever you want, when the waiter asks about desert, tell them that you aren't quite full yet, and would love to try their french onion soup you have been hearing so much about. Poke a hole in the cheese on top, and stick the mouse in. Wait till a waiter is near then plunge your spoon in only to find a drowned mouse. It might be nice to leave a tip, but the dinner will be taken care of.

Free the little guy!
