Laughter really is funny.
The first time I did stand-up comedy my only coherent thought afterwards was that I wanted to do it again immediately, and do it better.
Why is laughter so much fun?
As a psychologist, this is especially puzzling as pretty much everything we think about laughter is wrong.
So here are 10 things you, probably, didn't know about laughter.
1. Rats are ticklish
Want to see a rat laugh? Then tickle it. Rats laugh, chimps laugh and so do dogs. But rats aren't laughing at jokes. They laugh when they're playing, in the same way humans do, to show that they're happy and to encourage bonding.
The rats that played more, laughed more. And the ones that laughed more preferred to be around other rats that laughed.
This is evidence that human laughter has evolved from play vocalisation, a behaviour seen in many other mammals.
In humans, laughter has developed into an important emotional expression, used throughout many channels of communication. Think of the ways we try to convey laughter in text based media, like smileys and LOLs.
2. Laughter isn't about jokes
Ask adults what makes them laugh, and most will tell you it's jokes and humour. But they would be wrong.
Robert Provine, a psychologist from the University of Maryland found that we actually laugh most when talking to our friends.
In fact we're 30 times more likely to laugh at something when we are with other people.
Intriguingly, within these conversations, we are still not laughing at jokes: we laugh at statements and comments that do not seem on the face of them to be remotely funny.
It's a form of communication, not a reaction.
The science of laughter is telling us that laughter is less to do with jokes and more a social behaviour which we use to show people that we like them and that we understand them.

3. Your brain can tell the difference between deliberate and helpless laughter
In my lab we see the importance of laughter in our brain imaging studies. We compared staged laughter with the real thing.
media captionLaughter: real or staged, can you tell the difference?
Not only does your brain automatically tell the difference, but listening to staged laughter produces greater activity in an area called the anterior medial prefrontal cortex.
It's known to be involved in understanding other people's emotions.
It shows that we automatically try to comprehend someone's deliberate laughs, even when not instructed to do so.
4. Laughter is catching
Our brain scans also reveal that laughter is contagious. Even when someone is having their brain scanned, which is not really very funny, you can see their brain responding to the laughter by preparing their facial muscles to join in.
People find jokes funnier if they think they were told by a famous comedian.
