Penny: You know, I gotta ask; why didn't you just get a license at 16 like everybody else?
Sheldon: I was otherwise engaged.
Penny: Doing what?
Sheldon: Examining perturbative amplitudes in N = 4 Supersymmetric Theories, leading to a re-examination of the ultraviolet properties of Multi-loop N = 8 Supergravity using modern Twistor Theory.
Penny: Well, how about when you were 17?
Sheldon: I was otherwise engaged.
