One Day At The Patent Office

A young man walks into the Patent Office with a couple of his latest inventions under his arms:

`I'd like to register my new invention - a folding bottle.'

`Very interesting,' says the clerk. `What do you call it?'

'A fottle,' replies the young inventor.

`That's a pretty silly name, can't you think of something else?' asks the clerk.

`I'll think about it. In the meantime, I've got something else here to show you: my invention for a folding carton.'
'
And what do you call that?' asks the clerk.

`Oh, this is what I call a farton,' replies our young inventor.

`That is much too rude, you can't possibly use that name,' says the clerk.

`Damn, I guess you're going to hate the name of my folding bucket then.'
