Put it at the crash point in a race edit, after Sudden Suspense builds the tension and just before Cartoon Slip sells the fall. Follow it with Wrong Answer Game Show when the rider's mistake is the punchline, keeping the cow moment as the centre of the sequence.
About this sound
This is a very short, under-a-second angry cow moo from Road Rash 64, a sharp, gruff bellow that sounds startled and annoyed rather than gentle. It lands as a sudden, funny jolt, the kind of absurd interruption that makes a tense moment feel ridiculous. In the game it plays when a rider hits a cow during a motorcycle race.
