Place it at the end of a knock-knock setup in your edit, then follow it with Bruh for a flat reaction or Emotional Damage when the joke flops. For a bigger crowd gasp, use Oh My God Meme right after it instead.

This is a spoken knock-knock joke lasting about fourteen seconds, with the swear word bleeped out so the setup lands cleanly. The censored delivery makes it feel cheeky and awkward in a funny way, like a joke told just as someone realises it has gone too far. It works best as a quick, rude surprise that still stays safe to play around other people.
