Place it after the repeated action has already been shown once, so the repeat becomes the punchline, then follow it with Anime Wow to confirm the joke, and keep it away from the opening where the setup still needs room to land.
Über diesen Sound
This is a repeated sound effect lasting about 19 seconds, built around the same short phrase or noise coming back again and again, giving it a looping, insistent rhythm that is easy to recognise after one listen. It feels playful and slightly absurd, like a joke that keeps returning before you have finished laughing at the first version, which makes the repetition itself the funny part.
