Mr Nosey comes from Roger Hargreaves' Mr Men series, where his whole personality is being curious about everyone else's business and poking his long nose where it does not belong. That character trait explains why a short line about spotting a new bike fits him so well. Online, the clip circulates as a standalone soundboard effect detached from any full episode, shared in edits and chats whenever someone acts overly interested in another person's new purchase, plans or private moment for comic effect.
