Killer Button! (Jaws? hehe)

Don't worry, it doesn't kill your system or anything, it's for those "Yes/No" or "Register Now?" boxes, or just for a laugh!! If the user clicks "no" (or yes if you swap them) then the other button gets angry and goes after your cursor, with a snarl on its face and eyes that watch you! But don't worry! he's confined to the form.. or is he?
