Glenn Quagmire, who mostly goes by his last name, is one of the Griffins' neighbors on Family Guy. Quagmire is a bit of a lovable perv and is voiced by the show's creator, Seth McFarlane.
Though you could never tell by the way he acts, Glenn is actually an airline pilot. Oh and Quagmire has a huge thing for Lois and ruined Cleveland's marriage. I say don't leave him alone with your daughter or wife.
Peter: Well, my vasectomy is tomorrow.
Cleveland: You poor bastard. Sex is pointless without the potency.
Quagmire: Yeah. You take the venom out of the cobra, and what have you got? You got a... a belt!
Quagmire: What can I say? I really like watching her box.
Peter: That means two things.
