Dr. Strangelove's humor is generated by a basic comic principle: People trying to be funny are never as funny as people trying to be serious and failing. The laughs have to seem forced on unwilling characters by the logic of events. A man wearing a funny hat is not funny. But if the man doesn't know he's wearing a funny hat--now you've got something. The characters in Dr. Strangelove do not know their hats are funny.
