It's no secret that we here at CollegeHumor are big fans of It's Always Sunny in Philadelphia. In fact, Streeter just legally changed his name to Peter Nincompoop and Jeff has literally dozens of cats in his walls. But there's only one true way to prove your love of a show, and that's whether or not you can quote it. That's why we've created a 'Who Said It' quote quiz, packed with our favorite quotes from the gang. Call yourself a fan? Take our quote quiz and find out if you're on the level with Dayman…or if you've just been huffing way too much spray paint.
