this just reminded me of an episode of it's always sunny in philadelphia where one of the guys is making fun of the other's tattoo...the guy with the tattoo says "what's wrong with it? it's tribal?"
to which the other guy says "yea? what tribe are you from?"
Hahaha, yeah, Carlos Mencia had a similar thing, where he called on some white dude in the audience, asked him to show his tattoo (it was tribal), and then was like "Oh, what tribe are you from, CHAD?"
