Humor, sarcasm, irony, mockery, me.

Too many people are convinced a person can’t learn to be funny: Either we have the built-in ability to make people laugh, or we lack it and are never gonna get it.

Which means these folks obviously don’t understand how humor works. Anyone can learn to do anything. Maybe not well, but better than previously. Anyone can learn to be funny. They just gotta learn how humor works, and practice at it.

No, I’m not trying to sell you a class. I’ll even explain how humor works—for free.

Laughter is an automatic nervous reaction. People laugh when you expose them to the unexpected. Surprise ’em, shock ’em, play around with words a little, push things to a ridiculous extreme—or even frighten them, which is why some people laugh when they’re scared. The unexpected makes us laugh, and laughter floods the brain with feel-good endorphins. It’s actually a defense mechanism. But since it feels really good, people pursue laughter.

Unless of course their brain doesn’t produce enough of those chemicals; then they don’t bother. That’s why they’re humor-deprived: There’s no payoff. So they don’t see the point.

So how do we get people to laugh? Simple: Throw something unexpected at them. Like a monkey throwing poo. See what I did there? Unexpected. Shocking. Hence laughter.

But of course not everyone will laugh at it. Some of us won’t find it funny because they expect poo: Their dad was into poo jokes, their brothers were into poo jokes, their spouse is into poo jokes, their kids are into poo jokes, all their friends are into poo jokes, they’re up to their armpits in poo jokes. Poo wore off a long time ago. “That’s the lowest form of humor,” they’ll respond. It’s old, so it’s no longer unexpected. Nor funny.

And many are offended by scat or sex jokes. Or profanity. You notice how certain comedians swear a lot: Half their laughs come from the audience being so unused to all the dirty words, or the way they juggle those words for shock. They’re giggling about as much out of discomfort as surprise. But to the easily offended, these things aren’t funny whatsoever. Loads of people don’t find the Three Stooges funny at all: Three grown men beating the tar out of one another is horrifying, not hilarious. They have the same problem with Warner Brothers cartoons, Tom and Jerry, America’s Funniest Home Videos, or someone simply slipping on a banana peel or taking a pie to the face: They feel bad for the victims of these pratfalls. They’re not amused; they’re sympathetic.

But because laughing at the unexpected works so well, it’ll get people to watch terrible sitcoms and movies. Case in point: The Date Movie/Epic Movie/Disaster Movie/Scary Movie films. Critics can’t understand why on earth they sell so well. I do: Throw as much unexpected stuff at the screen as possible. “What’s she doing there?” makes a lot of people laugh. Even when it’s not actually funny.
