"You can go your whole life and not need math or physics for a minute, but the ability to tell a joke is always handy." --Garrison Keillor

A brain walks into a bar...

Imagine that you are sitting with a friend and suddenly, your friend's face starts to convulse involuntary. Her facial muscles, particularly her lips, stretch and she has a peculiar expression in her eyes. Oddly enough, nobody around you even turns his head to look as your friend chokes, trying to take broken, sudden inhalations, while her shoulders jerk and her entire body twists and shakes.Call the paramedics? Actually, this sequence of events is defined in medical dictionaries as laughter and scientists are unraveling how it plays out in the brain.
