This guy goes along to the Patent Office with some of his new
 designs. He says to the clerk, "I'd like to register my new
 invention. It's a folding bottle."
 
 "Ok," says the clerk. "What do you call it?"
 
 "A fottle."
 
 "A fottle? That's a stupid name. Can you think of something else?"
 
 "I can think about it. I've got something else though. It's a
 folding carton."
 
 "And what do you call that?" asks the clerk.
 
 "A farton."
 
 "That's rude. You can't possibly call it that."
 
 "In that case," says the bloke, "You're really going to hate the
 name of my folding bucket."
