When you can't find your gel pack that you would normally use to ice down a pulled groin muscle, what would be the next most logical choice?

Obviously frozen blocks of mozzarella cheese.

Piece of advice though... don't start talking on the phone to a special lady friend and forget about the cheese, cuz "man, I have to replace the block of cheese on my crotch. It's starting to go soft." isn't a very good pickup line.
