Season 6, Episode 8: "The Mom And Pop Store"

Let me ask you something.

Could you tell if teeth marks on somebody's arm...

...matched teeth marks on a pencil?

-It's possible. -Roll up your sleeve.

Somebody bit you?

Well, not just someone. Jon Voight.

-Jon Voight bit you? -Yeah, yeah.

The pencil. Get the pencil out of your mouth!
