Quote from Kevin Dorfman in Mr. Monk and the Game Show
Adrian Monk: What are you doing? What is that? Kevin Dorfman: It's Roddy Lankman's pencil. Yeah, those are his teeth marks. This is what you call a collectible. You can look, but don't touch. Adrian Monk: I don't want to touch it. Kevin Dorfman: Yeah, right. Seriously, don't touch it.
