the inventor and the beneficiary?

Today I was accosted by a homeless man in a red-checkered lumberjack shirt and one of those fur-lined hats with ear-flaps. He grabbed me by the arm as I waited at a crosswalk and gave me some advice. He said, "Remember, when it comes to anal sex, the man is the chicken AND the egg."

Let's be honest: he's either an X-rated Confucius or Eminem with a PhD in philosophy. But he brings up a good chicken-egg question: "Which came first? The ear-flap hat or the crazy person who wears it?"
