Norwegian Nutcracker

When you take a piano wire and tie it around the base of your nutsack and have a friend yank on the wire from behind, effectively making you fall forward and smack your head on a yellow fire hydrant.

No, other color fire hydrants are not allowed.

"So me and the boys were getting a bit experimental last night. But we should have known better- Every Norwegian Nutcracker ends with a trip to the hospital..."
