A Joke Trope...does that even exist? It's just a joke; would it really fit under Comedy Tropes?

Anyway, this is when you present a hypothetical scenario, then say something like "oh wait" and observe that it's actually true. Usually used to present a Take That.

Example: since I'm rather uncreative right now, I'll just pulll the one I found off of Google: "TO is an idiot if he thinks Vick would be better than Trent, oh wait he is an idiot."
