Deaf people and music
Saw a documentary once where a deaf guy listed dancing in clubs as part of his social life. Loved it. When asked how he knew what the music was doing, his (signed, obviously) reply was that he could feel the drums and bass vibrating, and thus knew what to do. Cut to scene of him socialising and he was like a young John Travolta on the dancefloor.

Ironically I've seen some people with perfect hearing dance like they'd never heard music before...
