Invention
Guy goes to the Patents Office with some designs.
He tells the clerk, "I'd like to register my new invention, a folding bottle".
Clerk: Oh yes, what do you call it?
Inventor: A fottle.
Clerk: That's a silly name, can’t you think of something else?
Inventor: I'll think about it,.. I've got something else here, a folding carton.
Clerk: And what do you call that?
Inventor: A farton.
Clerk: That's rude, you can't possibly use that name.
Inventor: Gee, you're going to hate the name of my folding bucket.
