If I start a joke with a question, then answer it as part of a joke. What is the answer of the joke called? Is there a specific term for it? I am pretty sure there is, but can't remember what it was. Also, what if the main part of the joke isn't an answer? What would it still be called?

I'm not sure if it's the 'main' part (after all, the setup is just as important) but you're probably looking for the phrase punch line (also spelled as a single word punchline):

It's often used for jokes which are like short stories; I'm not entirely sure if it applies to Q&A jokes as well (I'm not a native speaker).
