A man sits down in a movie theatre and notices that the man in front of him has brought his dog and it’s sitting in the seat next to him.
He thinks it’s unusual, but he likes dogs so he decides that as long as it’s not a distraction he won’t mention it.
The movie starts and pretty soon there’s a funny part. The dog makes some low woofing noises that sound like laughter.

A little while later there’s a sad part in film and the dog appears to be weeping. This continues throughout the film and the man sitting behind the dog is astounded.
When the lights finally come on he taps the dog’s owner on the shoulder and says, “I gotta say, and I know it sounds weird,

but it seemed like your dog really enjoyed this movie.”
The dog owner looks at the dog and nods. “I know, it really is weird,” he says, “because he absolutely hated the book.”
