Do you ever "air-scratch"?
Air-scratching...you know when you pretend you are scratching on the turn tables during a scratching part of a hip hop song. I am guilty of this myself, although I know I look ridiculous to the people that witness me in my car doing it. I usually hold one ear, then I scratch with the other. I think they should have air scratching competitions just like they have air guitar competitions.
Shrunken Fro: Don't try to bust me out. I do air-scratching, just not in your presence, I would look even more foolish if I was scratching with my mom in the car. I do play a mean air-drum set though, you're right.
