I saw a red Corvette Convertible right after the C5s came out in 1997 that had the plate: C54FUN
Then there was this woman in Ohio who got a plate that was randomly generated which read: BLO4SEX (Honk for Sex)
After that Ohio instituted the board that reviews custom license plate requests.

I guess they figured if the random generator came up with deviant things that the people of Ohio could come up with much worse things.
