Stereotyping is FUN!

It went down like this:
At work pouring drinks Liza looks pissed off.
So I says: You like pissed, what up?
Liza: People always think black people are mad if they're not smiling.
Me: Yup, that's right- it's cuz you black.
Liza: Oh well, people always think I look angry if I'm not smiling.

Later... Pouring drinks again.
Liza: Man, Europeans are always SO nice to me, I don't know why!
Me: It's because of Apartheid. Europeans have a lot of guilt over that.
Liza: Huh? What's that?
