Place it as the final beat right before your end screen, then follow with the outro song for the credits roll and add a bye bye mewing sting afterwards if you want two goodbye gags back to back in one closing sequence.
Über diesen Sound
A six-second voice clip built around the throwaway line chicken burger used as a nonsense excuse to hang up. Someone delivers the phrase like a final order instead of a goodbye, turning an ordinary call ending into a shared in-joke. The feeling is playful and awkward, the kind of abrupt exit friends repeat back to each other afterwards.
