Dick: Does anyone remember why we all decided to be white?
Harry: Oh, um, I went with white ‘cause I thought it'd be a little cooler in the summer.
Tommy: Well don't you remember, Dick? All the television signals that we picked up in outer space were filled with white people.

Tommy: Bryant Gumbel.
Sally: Right.
