I have seen quite a few bits of imaginary conversation sprinkled here and there. They usually diagram how a humorous exchange of conversation about a bizare situation would go. I am putting this under MPSIMS since it comes up in more situation then when talking about tv shows.
Look, I am not explaining this well so here is an example. It is from a thread I can’t find about what it would be like if Canada was to go to war with Mexico.
A canadian missle launching platform is crossing the border between Canada and the US, on it’s way to a hypothetical war with mexico
Border crossing guard: Do you have anything to declare?
Driver: You mean outher then this missle? No.
Any other examples?
