Place it at the end of an animal question or a fox clip, as the payoff, then follow it with a Funny Ha Ha Laugh to let the audience react. Use it once per edit so the joke stays fresh.
Über diesen Sound
This 10-second clip plays the bouncy, sung chorus from the novelty song, with playful animal noises and a bright electronic pop backing asking what sound a fox makes. It feels silly, upbeat and instantly familiar, like a joke everyone already knows the punchline to. It comes from Ylvis's 2013 viral hit 'The Fox (What Does the Fox Say?)'.
