3. 'Fake Plastic Trees'
They'll never admit it now, but many people first heard "Fake Plastic Trees" in the movie Clueless. It's in the scene where Cher comes home and finds her step-brother (and future boyfriend) Josh in her house. It's playing on the radio. "Yuk! Uh, the maudlin music of the university station," she says. "What is it about college and cry-baby music?" It's definitely a cry-baby song, especially the acoustic version used in the film, but it's also one of Radiohead's most anthemic songs. The first notes of it are guaranteed to send any crowd at a Radiohead show into absolute hysterics.
