Song: "Professor Booty" (1992)

Plain and simple, there are some moments in film history that beg to be sampled. This is one of those moments: "Yo, I don't hang out with those guys, I got nothin' to do with those dudes." "Man, I saw your female with them, too. What's up with her? I hear that she's been giving that stuff out to all them graffiti guys." "Yo, shut the fuck up, Chico, man!" "I'd paint three of those murals for some of that ass."

Wild Style (1983) is the movie and that crazy good convo is between Raymond a.k.a. Zoro a.k.a. Lee Quinones (in real life) and his smart-ass buddy Chico (Alfredo Valez). (The girl in question is played by Sandra "Lady Pink" Fabara.) These are the kind of movie quotes you repeat time and time again jokin' around with your buddies. Beastie Boys recognized the real, threw the snippet on "Professor Booty" and the rest is, as they say, history.
