Perhaps Oomis is referring to the following old tale:
A black and white panda bear walks into a restaurant. He orders a quick meal. After polishing it off, he pulls out a pistol, fires a few shots in the air, and walks out the front door.
Another patron turns to the owner and asks, “What was that?”
So the owner pulls out a poorly punctuated guide to animals, and flips to the P section. There it states: Panda bear: Eats, shoots, and leaves.
There is actually a cute grammar book titled, “Eats, Shoots and Leaves,” after that old joke.
