John Grogan: A dog doesn't care if you're rich or poor, educated or illiterate, clever or dull. Give him your heart and he will give you his.
When John picks his wife up at the airport, it's raining. But look at the people around outside, they are in T-shirts, in the sun, and not getting wet. Obviously the rain is being sprayed on the car.
The author of the original book, John Grogan, and his family have a cameo appearance. They are looking on as Marley flunks out of obedience school.
