I have a lotta fun with my negroid(scientific term) nephew. My wife says she's not racist, but when I get him to call her momma in public, you can see the f$%king horror on her face!!!! Then she starts rambling about "nephew not son", "adopted", "not that it matters" and my favorite "I like black people, just not in that way!!".
I would say the medical field has the best sense of humor.
