Cleveland: Hey Quagmire, how was your date last night?
Quagmire: Cleveland, it was amazing. You know what I discovered last night? Women have a fourth hole.
Joe: What?
Quagmire: Yeah, I mean it's only visible if you're looking from exactly the right angle, like the entrance to Hogwarts. But ya gotta believe that it's there.
Peter: Man, I envy you single guys. No families, partying whenever you want. These are the only people I get to party with. (holds out his wallet, with a picture of the kids)
Quagmire: (Pointing to Meg) Oh, that's where the fourth hole is, right there. Right there in the back of the knee.
