I dated a black girl for several months. After we broke up, I thought I would like to date someone from a different race just for something different. Maybe nothing wrong with that in itself, except that I have never thought that after dating a white girl.
Dunno, can't really think of anything else.
EDIT: Oh, I thought of a bad one. In college me and a few friends were going to change the labels on the cafeteria milk dispenser, just as some stupid joke. Changing it to things like goat milk and whale milk and whatever. Someone suggested we change the chocolate milk to to n***** milk. Although it wasn't my idea, I still laughed at how inappropriate of a joke it was and didn't do anything to discourage it. We didn't actually make that label, thank god.
