The line comes from AquaticNeptune's SpongeBob Plug 'n' Plays with Shrek, a fan-made crossover that mixes SpongeBob characters with Shrek in a deliberately absurd setting. Lifted as a short standalone clip, it travelled through soundboards and short-form edits because the question works without needing the original scene. Creators keep returning to it whenever a name, title, or label feels too strange to pass without comment, making it a handy shorthand for disbelief.
