Put it at the very end of a short setup as the punchline, then follow it with the Law & Order Dun Dun sting to close the scene. For a group-chat version, open with the DJ Airhorn Sound Effect before the setup so the final line lands as the payoff.

This is a very short Hank Hill voice clip, lasting under two seconds, that ends on the phrase “about to bust.” His plain, serious delivery turns awkward in an instant, which makes it feel funny and deliberately uncomfortable rather than shocking. It comes from King of the Hill, where Hank is the main character, and that contrast is what makes the line work as an ironic reaction.
