Glenn is the sex-crazed next door neighbor and one of Peter Griffin's best friends. He is often seen trying to pick up women for anonymous sex, whether it be a cheesy date with an unlucky woman or some form of a blowup doll. One of his catch phrases are "Giggity giggity goo".
In Family Guy episode "Baby Got Black," Peter Griffin and the boys are doing a contest to see who stays up the longest throughout the night, Peter Griffin is tired and imagines Glenn Quagmire as a toilet, probably the most amazing thing to happen in Family Guy
Person 1: Yo dude i just Quagmire turns into a toilet
Person 2: HOLY SHIT!!!!!! LIKE FOR FREE IPHONE!!!!!!!!
