The post about the whiteness project reminded me of Black Folk Don't. I think it's a pretty cool series if you haven't seen it:

"Black Folk Don't..." is an open conversation that invites everyone to take a second look at the grey areas between us all, no matter the race, and most importantly to do it with a sense of humor. This documentary web series is a special presentation of BlackPublicMedia.org, directed and produced by Angela Tucker, with support from the Corporation for Public Broadcasting.

The first episode is about tipping, and there's a more recent video about feminism. Anyways all of the episodes can be found here: Black Folk Don't (PBS)
