This man 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, replies the inventor."
"A fottle? That's a stupid! Can't 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", replies the inventor.
"That's rude. You can't possibly call it that!"

"In that case," says the inventor...
"You're really going to hate the name of my folding bucket."
