You don't see UPS drivers having this kind of trouble.

Check out this poor FedEx driver, who gives his all (which is still not nearly enough) while trying to stop his truck from rolling away from him.

Making the scene even more amusing is the fact he has an audience. The pooches in the yard seem to be entertained by the show. Hey, it's not their insurance rates that will be affected, so why wouldn't they enjoy it?
