Boy, doesn't it look like Adam Sandler and his old pals had a blast making Grown Ups, hanging out on a lake, riding water slides, peeing in pools, and being paid handily for it?

Here are ten films that should have been turned into home movies for the actors to enjoy privately, rather than subjecting the filmgoing public to them.
