The line comes from Doctor Who, spoken by the Eleventh Doctor, played by Matt Smith, to his companion Amy Pond, played by Karen Gillan, during his tenure from 2010 to 2013. It riffs on the classic Come along phrasing used by earlier Doctors, updated with Pond as a nickname. Clips of the quote circulated on YouTube compilations and Doctor Who fan edits before moving to TikTok and soundboard sites as a short invitation meme. It endures because it packs fandom recognition and cheerful momentum into just over a second.
