Was Thindy ever called a "snitch" or was that just from the Brady Bunch Movie?

Marsha and Peter = Benedict Arnold

Peter = Peter the Perfect; "you stupid kid"

Peter = Peter the Magnificent (when he was a magician. Maybe I am wrong and it was "Peter the Great," or "Peter the Something else." Let me know)

Then there's the one the only, Johnny Bravo.

Didn't Greg call Bobby a "dumbhead" in the last episode (the orange hair)?
