A man follows a woman, who has a dog on a leash, out of a movie theatre. He stops her and says, "I'm sorry to bother you, but I couldn't help but notice that your dog was really into the movie. He cried at the right spots, he moved nervously in his seat at the boring parts, but most of all, he laughed like crazy at the funny parts. Don't you find it unusual?"

"Yes," she replied, "I found it very unusual. He hated the book!"
