The retort to any person'
s lame
excuse of "I
know what you are, but what am I?"
Can be easily out-dissed by the secondary retort, "Takes one to no one."
Person 1: I
guess you're a
garbage man.
Person 2: I know what you are, but what am I?
Person 1: A garbage man.
Person 2: I know what you are, but what am I?
Person 1: A garbage man.
Person 2: Takes one to know one.
Bystander: Ooo, well-
played, sir.
