I think the silliest show I saw was something called the Banana Derby where monkeys served as jockeys riding on the back of dogs. (Click on the photo, it's worth a closer look.) There were two supposed races but, the dogs just sort of sauntered around the course never even breaking into a light trot. After the race, people queued up to have their picture taken with one of the monkeys at $10.00 a pop. That obviously, was the real money maker.
