Dialogue that sounds like it is referring to a certain topic, only to end in a comedic twist.
Rolling Updates, Needs More Examples
A type of Bait and Switch, used for comedy. A character will describe or react to something in a way that looks like it's heading toward an obvious conclusion, but instead it ends differently. The key is the build up to the punchline. The longer the character goes on, the more ridiculous it becomes when their actual topic is revealed. When exaggerated, the character will expound with such specific detail it seems like they couldn't possibly refer to anything else, and yet still will somehow. Compare with Non Sequitur, which will not make any logical sense and feel completely random. In this trope, the final comment will follow some sort of logic (if at least only to the person who brings it up), but the dialogue leading up to it will appear as if it's heading in another direction. A Bait-and-Switch Comment is when a sentence gains a different meaning only after being said in full. Innocent Innuendo and Stab The Salad are subtropes.
