Chapelle did a skit on this some years back, and yeah, the white folks tended to be absurd dancing to drums or horns like Blacks or Latinos. But give'em guitar riffs and suddenly the tables turned...
There’s more than one aspect of rhythm. Can’t dance well but I have the best singing rhythm of anyone I go to karaoke with, and I can finger drum super accurately, but with actual drumsticks I’m hopeless.
