Laugh till it hurts

You know when someone falls down and you have a natural tendency to laugh.  Why do we laugh at other’s misery?

YorkNBeans posted this video about a news reporter who gets attacked by a leapin’ lizard (a Little Orphan Annie reference for all you over 90).  His almost seizure sounds and saying “What the fuck” on air made it priceless.  Had to watch it about 5 times.
