Place it at the end of a short gag, just after the visual surprise, then follow it with a funny ha ha laugh to keep the energy going. For a failed attempt, put a ba dum tss drum sting before it so the banana lands as the payoff.

This short clip, just over five seconds long, has a Minion voice stretching out the word banana in a squeaky, playful gibberish delivery. It feels silly, bright and harmless, turning an odd visual or sudden cut into a light cartoon joke. It comes from the Minions in the Despicable Me films, where banana became one of their best-known lines.
