Place it immediately after the punchline, at the end of a short gag, then follow a second bad joke with the Law & Order Dun Dun for a mock-serious turn, or save the DJ Airhorn for a later reaction in the same edit.
About this sound
This is a very short, polished French television jingle linked to Michel Denisot, lasting just over a second and built like a bright broadcast sting. It feels cheeky and knowing, like a studio wink that tells listeners a joke has just landed. Shared widely in French meme spaces and chat audio, it is used to frame a corny line as a deliberate, lightly theatrical gag.
