I did yesterday on the way home from work. It was some fancy expensive car. I don't remember what kind, but the name/model started with the letter T and ended in a vowel. Also, the logo was sort of a T.
Anyway, their plate said BETRDNU. I was just really annoyed that this guy (or girl) thought they were better than me. If I was going to get in an accident on the highway and rear-end another car, I'd want it to be that one!
