'Cause gdnet has one where you are a kid on a skateboard trying to catch the boxes containing PSPs that are falling out of a big rig going at high speed!
It was done pretty well!
I also like the one where you shoot the cowboy, and the one where you kiss Brad Pitt and make his eyeballs all heart-like.
EDIT: The batman one sucks! You can miss hime entirely and still get the popup window!
