THE LION AND THE BOOK
Two explorers were on a jungle safari when suddenly a ferocious lion jumped in front of them.
"Keep calm," the first explorer whispered. "Remember what we read in that book on wild animals? If you stand perfectly still and look the lion in the eye, he will turn and run."
"Sure," replied and his companion. "You've read the book, and I've read the book. But has the lion read the book?"
