concise versions of children's favorites: The Cat in the Hat
An oddly dressed stranger comes over when mom isn't home, insisting that mom is a friend who'd want the kids to let him in to play. Two subverbal, possibly violent friends accompany him. Kids learn the important lesson that when you invite freaky strangers in (over the protest of their boring scold of a goldfish) it's fun to engage in hazardous stunts and wreck the house with them, because strangers also magically clean the house up the second before mom comes home. For it is fun to have fun, and the linkage of action and consequence is nothing but fishbowl superstition.
