Smart puppy
A guy went to the cinema one day and noticed an old man with a dog in the front row. It was a sad, funny kind of film and the guy noticed that during the sad parts the dog cried his eyes out, and during the funny parts, the dog laughed its head off.
This happened throughout the film. After the film ended, the guy decided to go and speak to the old man.
"That's the most amazing thing I've seen," he said. "That dog really seemed to enjoy the film."
The old man turned to him and said: "Yeah, it is amazing. He hated the book."
