Put up references to GF movies you've seen in a book movie or TV show..I know there's a lot out there.
Anyways, apart from the apparent new ones,(Like in Analyze this and Zoolander) the one that sticks in my mind is from that TV show, Jack and Jill. You know, with Amanda Peet?
Anyways someone was receiving a message on her machine, from a geek asking her out to a party- it was like this-
"Hey Audrey, let's go to this reeeaaally cool pary my friend Dave's throwing, y'know, we all have to dress up as our favorite character from GF, i was thinking I could be Michael and you could be Kay although i'd understand if you wanted to be Connie, they say she's a more interesting characters, like in the sequel blah blah blip geek trash fanboy slurrr"
