A book and a joke

Saw this article about a book in the NYT and I liked the joke about the Panda.

"Truss, a self-described stickler, a woman incensed by the gratuitous apostrophes in grocery-store signs that say "Apple's for Sale" or "We Have Lemon's and Lime's and Video's," had achieved the not inconsiderable feat of making punctuation hot. She turned the apostrophe into a form of mass entertainment.

"Eats, Shoots & Leaves: The Zero Tolerance Approach to Punctuation" went on to sell some three million copies in hardcover. It fared well even in foreign languages, including Japanese and Swedish, the go-to grammar book for those studying English as a second language. In America, the book easily held its own against "Harry Potter," diet books and the plethora of pre-election screeds, remaining on the New York Times best-seller list for 44 weeks.

The book's title, by the way, refers to a joke about a panda that walks into a cafe. He eats a sandwich, fires a pistol into the air and then leaves. On his way out, he tosses a wildlife handbook at a bewildered waiter, who understands everything when he turns to the section marked "panda" and notices a grievously misplaced comma: "Eats, shoots and leaves."
