So there are these two muffins baking in an oven. One of them yells, “Wow, it’s hot in here!”And the other muffin replies: “Holy cow! A talking muffin!”

Laughter, a topic that stymied philosophers for 2,000 years, is finally yielding to science. . . .
[M]ost laughter has little to do with humor. It’s an instinctual survival tool for social animals, not an intellectual response to wit. It’s not about getting the joke. It’s about getting along.
. . . Robert R. Provine [a neuroscientist at the University of Maryland] . . . went out into natural habitats — city sidewalks, suburban malls — and carefully observed thousands of “laugh episodes.”

He found that most speakers, particularly women, did more laughing than their listeners, using the laughs as punctuation for their sentences. It’s a largely involuntary process. People can consciously suppress laughs, but few can make themselves laugh convincingly.
“Laughter is an honest social signal because it’s hard to fake,” Professor Provine says. “We’re dealing with something powerful, ancient and crude. It’s a kind of behavioral fossil showing the roots that all human beings, maybe all mammals, have in common.”
The human ha-ha evolved from the rhythmic sound — pant-pant — made by primates like chimpanzees when they tickle and chase one other while playing. Jaak Panksepp, a neuroscientist and psychologist at Washington State University, discovered that rats emit an ultrasonic chirp (inaudible to humans without special equipment) when they’re tickled, and they like the sensation so much they keep coming back for more tickling.
He and Professor Provine figure that the first primate joke — that is, the first action to produce a laugh without physical contact — was the feigned tickle, the same kind of coo-chi-coo move parents make when they thrust their wiggling fingers at a baby. Professor Panksepp thinks the brain has ancient wiring to produce laughter so that young animals learn to play with one another. The laughter stimulates euphoria circuits in the brain and also reassures the other animals that they’re playing, not fighting.
“Primal laughter evolved as a signaling device to highlight readiness for friendly interaction,” Professor Panksepp says. “Sophisticated social animals such as mammals need an emotionally positive mechanism to help create social brains and to weave organisms effectively into the social fabric.”
. . . . Laughter can be used cruelly to reinforce a group’s solidarity and pride by mocking deviants and insulting outsiders, but mainly it’s a subtle social lubricant. It’s a way to make friends and also make clear who belongs where in the status hierarchy.
Which brings us back to the muffin joke. It was inflicted by social psychologists at Florida State University on undergraduate women last year, during interviews for what was ostensibly a study of their spending habits. Some of the women were told the interviewer would be awarding a substantial cash prize to a few of the participants, like a boss deciding which underling deserved a bonus.
The women put in the underling position were a lot more likely to laugh at the muffin joke (and others almost as lame) than were women in the control group. But it wasn’t just because these underlings were trying to manipulate the boss, as was demonstrated in a follow-up experiment.
This time each of the women watched the muffin joke being told on videotape by a person who was ostensibly going to be working with her on a task. There was supposed to be a cash reward afterward to be allocated by a designated boss. In some cases the woman watching was designated the boss; in other cases she was the underling or a co-worker of the person on the videotape.
When the woman watching was the boss, she didn’t laugh much at the muffin joke. But when she was the underling or a co-worker, she laughed much more, even though the joke-teller wasn’t in the room to see her. When you’re low in the status hierarchy, you need all the allies you can find, so apparently you’re primed to chuckle at anything even if it doesn’t do you any immediate good.
