Hypothesis

Earlier this morning, I said to someone who was worried about typing topless:

You'll be joining a log line of typists, including Wood Allen, who liked to type "naked" or "topless".

I've even seen a few typewriter shops selling typewriters without the external shells. I'd a lot harder to keep them dust free, but it can certainly be fun. It's an fun, easy, and fascinating way to sell off a machine that's missing some screws or has dented/damaged panels.
