Philosophy Joke: Low-Hanging Fruit

So I fully admit that this is sort of an obvious joke for philosophers, and I have doubts that I'm the first to come up with it. But I'm claiming independent invention. I made this up while I was working on a paper today. Here it is:

Luke Skywalker is sitting in the swamp reading some action theory. He scratches his head, puzzled, and looks over at Master Yoda, who is cooking some beans.

"Master Yoda...", whines Luke, "I don't quite understand. When is it that I actually do something? I mean, if I start to Φ, then I haven't Φ-ed, yet, so I'm not really Φ-ing. But if I stop Φ-ing, then I'm not Φ-ing any longer, I've only Φ-ed. How do I Φ?"

Master Yoda looks over and says, "Told you this already, I have. Do, or do not. There is no Φ."

I'm here every night...
