You guys showed crazy restraint in not referencing No Diggity with the mmmhmmmm guy.
I'll say this for the gum mutilators, they've got a pretty sweet gig worked out. The more you stab yourself with sharp things, the more time you're gonna have the spend at the dentist, where presumably they'll be poking around trying to figure out what the hell happened in your mouth. It's an endless cycle of bliss.... until you start hitting bone.
