Have you seen the movie "Constipated?"
It hasn’t come out yet.
Alright, listen up, dummy! The joke is that the movie is called "Constipated," and constipated means you can't, uh, 'come out' with your poop. And movies 'come out' when they are released! See? It's funny because it uses the phrase "come out" in two different ways. You probably still don't get it, do you?
