Place it as the payoff at the end of a heat gag, after a Yeah reaction sets up the complaint and before a Funny Ha Ha Laugh closes the scene. Keep it as the single reaction in the sequence, then move straight to the next visual gag so the joke stays tight.

This is a very short Persona 5 voice line, lasting under a second, in which a character simply says that it is hot. The flat, overheated delivery makes it feel sweaty, exasperated and relatable rather than dramatic. Taken from Persona 5, it works as a tiny burst of comic discomfort that lands best when the heat itself is the joke.
