There is a weird phenomenon going on in Britain: The hottest book on the market is about ... punctuation. It's called Eats, Shoots and Leaves and over 500,000 people have purchased it.

The story behind the title describes why punctuation is so important:

A panda walks into a bar. He orders a sandwich, eats it, then draws a gun and fires two shots in the air.

"Why? Why are you behaving in this strange, un-panda-like fashion?" asks the confused waiter, as the panda walks towards the exit. The panda produces a badly punctuated wildlife manual and tosses it over his shoulder.

"I'm a panda," he says, at the door. "Look it up."

The waiter turns to the relevant entry and, sure enough, finds an explanation.

"Panda. Large black-and-white bear-like mammal, native to China. Eats, shoots and leaves."
