Place it right after the strange explanation, as the final beat that accepts the idea. Follow it with Bruh when the group realises what was just agreed to, then cut to the next scene for the payoff.

This is a very short voice clip of Patrick saying "that makes sense to me" as a simple, deadpan agreement. It feels dry and agreeable, turning a strange or unlikely idea into something that sounds perfectly reasonable. The humour comes from how readily he accepts it, without surprise or argument, as if the strangest plan in the room was obvious all along.
