Jolly good show is one of Pops's best-known catchphrases from Regular Show, the Cartoon Network animated series that ran from 2010 to 2017. Pops, the show's kind-hearted and eccentric lollipop character, often used the line to show sincere delight at something impressive or amusing. Short clips of the phrase later circulated on soundboards, video edits and social media, where its old-fashioned politeness became part of the joke. It remains popular because it offers a warm, non-sarcastic way to celebrate a moment without needing any context from the episode.
