The clip comes from a Chris Moyles prank feature in which John phones another taxi company while staying in character as Shaggy, the laid-back Scooby-Doo character voiced in the cartoons with a distinctive shaky, youthful tone. Labelled Part 2, it circulated as a follow-up to an earlier call and was later shared on soundboards as a standalone meme clip. Its lasting appeal is the recognisable impression rather than the booking itself, which is why creators reuse it for prank and reaction edits long after the original radio bit.
