What is call back humor?

Callback humor is a type of comedy where a comedian or a storyteller refers back to a previous joke or incident in a later part of their act or story. It creates an additional level of humor as it catches the audience off-guard, without making them expect it. Callback humor is often used to reinforce a previous joke or to tie together unrelated jokes. This technique requires a great deal of skill and timing on the part of the comedian or storyteller, as they must remember the earlier joke and reintroduce it in a way that is both relevant and funny. It is a commonly used technique in stand-up comedy and is often used to create a recurring theme throughout the performance.
