Anyone ever see the movie See No Evil, Hear No Evil with Richard Pyror and Gene Wilder? Pryor plays an in denial blind guy and Wilder is deaf and reads lips and they are framed for a crime. It has to be one of the funniest movies of its kind I've seen. Pryor plays darts (as a blind guy) at the bar. Also, the female criminal asks him if he has any last requests, and he says "I suppose a f*** is out of the question?" and you can see her genuinely laughing like it was ad libbed.
It also has a good message about overcoming handicaps and playing up your strengths.
