Weezer first landed on MTV in the summer of 1994 with their video for "Undone – The Sweater Song," which simply showed a pack of wild dogs and the group playing the song. But they truly broke through a few months later with "Buddy Holly." Spike Jonze (still five years away from making his first film) had the brilliant idea to put the band in Arnold's Diner from Happy Days, complete with a cameo from Al Molinaro himself. Jonze sifted through thousands of hours of Happy Days clips to find the perfect footage to use in the video, including Fonzie dancing. The effect was seamless and MTV played the video over and over and over. It was the single biggest factor in breaking Weezer.
Watching the video brings forth an almost unprecedented level of nostalgia. Happy Days itself is a 1950s nostalgia show, but now it brings back the 1970s, also. The video is a 1990s classic, too, so it manages to evoke nostalgia for three different decades in a single three-minute video. That's a remarkable achievement.
