The line comes from the 2002 comedy film The Master of Disguise, where Dana Carvey plays Pistachio Disguisey, a man who uses elaborate costumes to blend in. Dressed as a turtle, he delivers the pun-filled question while trying to gain acceptance, turning a silly disguise into one of the film's most quoted moments. Years later the clip spread through soundboards and meme edits, where its mix of earnest delivery and obvious wordplay made it easy to reuse. It endures because the joke needs no setup and instantly signals not quite belonging.
