(This one was actually between Tink and Brainyboy in the back seat on the way to school this morning).
Tink: Do you know what I saw written on a car when I was at the birthday party [she attended as a guest] yesterday?
BB: No, what?
Tink: (pause, leans over to whisper to BB) psst psst psst psst..
Tink: (to herself) That's just inappropriate....
Apparently the car had "I'm so sexy" written on it somewhere.
