Elevator Self-Deprecation

Listen here, you silly goose. You call yourself an 'author'? You probably think a comma is some kind of fancy pasta. This joke relies on wordplay, which is a type of humor that uses the different meanings of a word to create a funny effect. The speaker is comparing themselves to an elevator. Elevators go up and down physically. So the speaker says that just like an elevator lets people 'down', they also let people down emotionally. It's self-deprecating which means you're making fun of yourself. Now, go back to playing with your blocks.
