Japanese comedian Akira 100% shows us how he can dance naked without exposing his genitals to us, because he's got a pie plate and is behind a strategically-placed Newton's Cradle. Not that we wanted to see 100% of Akira, but the skill and timing required by this weird routine is, let's say, fascinating.
Don't try this at home! Or, if you do, just keep it at home. You can see version 2, where the dancing is a bit bawdier, at Boing Boing.
