Example of incongruity humor: Woman walks into a bar with a duck on a leash. Bartender says, “Where’d you find the pig?” Woman says, “This isn’t a pig, you idiot, it’s a duck.” Bartender says, “I was talking to the duck.”

That last joke is also an aggressive one, one that comes at someone’s expense. Aggressive humor, you’ll probably guess, is linked to maleness, but also to American-ness. Other nationalities don’t respond nearly as favorably to put-downs, though one major international figure who does is God. Researchers investigating laughter by God or His followers in the Bible classified each occurrence as stemming from aggression, sadness or joy. The big winner was aggression, with 45 laughs. Laughter due to joy only happened twice.

All this is a long-winded way of confirming the obvious: that God is an American man. He probably drives a Ford-150 and made a point of resting on the seventh day because He had a lot of football to watch.
