Season 8, Episode 9: "The Abstinence"

So, what did you do?

I told her I would have to think about it.

But ultimately you're gonna choose in favor of sex, right?

I don't know. Perhaps I can better serve the world this way.

You mean, not subjecting women to your sexual advances?

A simple joke from a simple man.

So you're never gonna have sex again?

...there was a pretty good chance I was never gonna have sex again anyway.
