JD needs a date. Badly. But he might be (Read: is) setting his sights a tad too high if he thinks he can get Jenny McCarthy, especially in light of Howard's revelation that JD was willing to let Jenny pee on him.
JD then quickly explained that they were trying to think of ways to punish Gary for double-booking Jenny last month, and one idea was to have Jenny pee on Gary. JD, however, doesn't think that's a punishment at all. In fact, he'd enjoy it!
Howard then defied Jenny to find one thing on JD that she liked, to which she responded to by looking JD up and down and saying, "I like your glasses."
Gary, of course, still needed to be punished, but he was not peed on; he had to kiss Jenny's feet instead, which is not a bad deal at all.
