A girl comes home to make herself a sandwich and chat with her mom after a long day on a class trip to the farm. The girl's story works backwards at the beginning. Slowly, tantalizingly, she leaks out the details of the trip. After all, it didn't really get exciting until the cow started crying. When asked, the girl admits that the cow was crying because the farmer hit a haystack on top of her. Why did he do that? Well, he was distracted by the pigs that had overrun the bus. And so it goes. Slowly the mother gets the full story of how fellow classmate Jimmy took his boa constrictor (a dew-eyed sweetie pie of a snake) to the farm and how all havok broke loose as a result. In the end, Jimmy left the boa there and adopted one of the pigs that never left the bus. -Aamazon.com-
