Shaggy is the famously nervous, hungry sidekick from Scooby-Doo, a character audiences have recognised for decades, which is why a single impression can carry a whole joke. This clip comes from a run of prank calls in which John phones businesses while staying in character as Shaggy, with this instalment aimed at another taxi company. Shared as a short standalone sound, it fits the soundboard format perfectly: listeners get the reference instantly, the premise needs no explanation, and the brief call works as a repeatable gag in memes, streams and reaction videos.
