These Hands are Registered as Deadly Weapons

I think the first time I heard the phrase "These hands are registered as Deadly Weapons" was on Happy Days, I think it was an episode where Tom Hanks wanted to beat up Fonzie.

I never thought much about it but there is a place where you can register your hands (or anything else) for $5 and they send you a wallet card with a pic of the registered body part if you like, a certificate and enter you into a database.

if your interested it is

DeadlyHands.net

It's worth it for a laugh.
