Reminds me of something I saw on Johnny Carson's show (apparently it's not on the internet, though).
Johnny is doing Q&A with a guest, at his desk, and Johnny takes two fingers and "walks" them across the desk, clearly imitating a human's legs or a person walking.
He asks the guest if he knew what that represented, and the guest shrugged, so Johnny answered for him: "MAN."
Then Johnny puts the middle joints of those fingers down in contact with the desk's surface. It looks like the "person" was know kneeling, and not moving.
He asks the guest if he knows what THIS represents.
The guest says: "WOMAN."
Johnny turned red and the audience gasped and roared with laughter.
(I don't remember the rest, or what point Johnny was trying to make. Perhaps it didn't get any farther than that, with the "woman" figure kneeling and the "man" figure standing.)
