Marty Feldman's Pinched Mouth

Marty Feldman nearly fell into the Underbite category but I made a judgment call and placed him in the Pinched Mouth family due to his lip size and the way his mouth recedes into his head. He also did a great job of concealing his teeth so I wasn't able to get a convincing image of him being underbitten.

If you've never seen Young Frankenstein, do yourself a favor and watch it this weekend...you'll be a better person for it.
