What makes people laugh?

Some type of body harmones....hehehehe! Well I believe something that make us happy instantly makes us laugh.

The most unfunniest thing can often be funny. It’s down to circumstances.

When you see dwarfs, when you see a tall man and his wife who is too short, when a short girl dancing with tall man and when one sees situations like this, one would laugh. People may also laugh at others doing foolish things. What is important is laughing is good for health. It imporves one's lungs. There is a park nearby my house. I go for a walk in the morning. There are 50 to 75 people laugh for nearly 20 to 30 minutes. That is laughing clubs organised by morning walkers. I am not sure this kind of artificial laughs will result in improving the lungs.

I have seen people keep smiling all the time. But if a person keeps on laughing, myself and my friends call these persons as "mental". But I was told there is something like laughing gas? Is it really there and how it is useful?

stand up comedy.......... or series like "the bean"

funy jokes make people smile and laugh

anything funny but not dirty, laughing releases the same chemicals and making love or chocolate, there is something now called laughter therapy.

Fart jokes are always funny.

a pleasant surprise is what makes your mind smile .. thats the same case with jokes as well .. its all about the surprise factor

If one is putting a joke on himself....it is the funniest part and enjoyable to all.
