The vanity plate is a notorious platform for people to get their bragging out (it has vanity right in the name!), but when you bring that boasting opportunity to a major urban center, all bets are off. You're going to get some ridiculously egotistical stuff.

Surprisingly, they weren't too hard to find.
So the next time you find yourself poised to make a dumb blonde or Beverly Hills joke, just remember "PSOR1S1S."
