My answer to the Vagina Monologues. That minor in philosophy really paid off!
Thracymachus: Socrates, what is the ideal length of a man’s penis?
Socrates: Oh, I know nothing of such matters. What would you, Thracymachus, say is the finest size?
Thracymachus: I would say that I am of the opinion that a large penis is preferable.
Socrates: But surely you grant that if a penis is too large it will become useless.
Thracymachus: I do.
Socrates: And therefore a penis that is too large is inferior to an overly small penis.
Thracymachus: Naturally.
Polemarchus: But what if, by Zeus, one has an exceptionally large penis but one’s wife posses an exceptionally deep cavity. In such a case, one would have superior intercourse as well as bragging rights.
Socrates: Of course.
Thracymachus: Socrates, it looks as though you have been contradicted.
Socrates: Not at all, Thracymachus. While the possessor of such a member would undoubtedly have superior intercourse, a penis of this size would by no means fit into the mouth, thereby rendering fellatio impossible. Is this a superior scenario?
Polemarchus: Certainly not, but can we not all agree that a large penis, but not such a gigantic member as one would find on the statue of Pan in the temple is, in fact, the best length for a penis to be?
Socrates: Perhaps, but what if one is to sleep with a virgin? Possessing a large penis would certainly make intercourse painful, if not impossible.
Thracymachus: Ah, so then the best length of a penis would be the best length for a particular occasion.
Socrates: It would seem so.
Polemarchus: But we are now even farther from a resolution than when the discussion began. There must be an answer to our query.
Socrates: There may be one, but we seem unable to uncover it. Can you?
