The line comes from Thomas and Friends, the long running children's series about engines on the island of Sodor, and is spoken by James, the red tender engine known for his pride and short temper. Clips of dialogue from the show have been lifted for years as a meme reaction clip, because the earnest delivery contrasts with adult online humour. This quote survived on soundboards and in short edits for the same reason: it is instantly clear, needs no setup, and can be dropped into almost any failed joke.
