Glenn Quagmire

Not only notable for his prodigious libido, he is also the candidate for Internal Affairs, he likes affairs and often has them. Quagmire's sexual obsession and complete lack of morality have made him one of the most popular party members. Glenn is the sex-crazed next door neighbor and one of Peter Griffin's best friends (though Peter is completely oblivious that Quagmire is in love with his wife, Lois.) MacFarlane describes Quagmire as "a despicable human being who is still caught in the rat-pack era". When he is not hanging out with the guys, Quagmire 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.

He has several catch phrases, including "OH!", "All riiiight", and the nonsensical phrase "Giggity giggity giggity" (which has expanded to "Giggity giggity goo" and later to "Giggity goo gaa" and even "Giggity giggity giggity giggity giggity giggity giggity goo;"). Many times, these phrases are accompanied by suggestive pelvic-thrusting motions, headbanging, or both.

Quagmire's house, while ordinary-looking from the exterior, is stocked with gadgets stereotypically associated with swingers from the 1960s and 1970s, such as a mirrored bedroom ceiling, lava lamps, a cabinet-style record player, "disco-like" decorations that fold out from panels in the walls at the press of a button, and dozens of revolving beds. The rest of the interior decor also follows the same sixties-retro theme, with abstract paintings, a sunburst clock and stylish period furniture. He keeps an "abort" button behind his home bar, which returns his decor from his swinging bachelor pad to a more "normal" look.
