Universally over-used man.

This is officially the most overused drawing. I love it, but it's been used so much it's degrading. Last seen neutered on the cover of R C Sproul's Table Talk, As a corny Werewolf diagram in the otherwise excellent Harry Potter 3 movie, and about a million other places.

And now I will go read Harry Potter 6 (which is free of stolen Da Vinci drawings) until I fall asleep.
