According to me we laugh because when something strange fun happens. Something funny which we don't expect but it happens suddenly.

Laughter is a response from the conscious brain. Acidity is a form of indigestion and sometimes a serious medical condition. Laughter is a product of logic. Perhaps that's why so much logic is laughable. See what I mean?
