This music is best known as the theme associated with HBO's Curb Your Enthusiasm, which premiered in 2000 and made the tune a long-running comedy cue. Online, it spread far beyond the show as a meme soundtrack for awkward timing, public embarrassment and anticlimactic endings. Creators often drop it after a bad decision, a busted lie or an unfortunate reveal because the upbeat arrangement makes the failure feel even funnier. Its staying power comes from how quickly listeners understand the joke setup.
