-Some- of wrestling is fake. Yes when a person is laying on the ground and the other wrestler is "stomping" on him, the wrestler is really sliding their foot on their side. There are the times where it is in no way fake. As Sonic said, taking a chair to the head. Over the years of wrestling I have watched I have seen people hit with bamboo sticks, garbage cans, thrown into cars (hard enough to dent the hood), etc etc.
Do some research before saying Wrestling is all fake. Find out whoe Mick Foley is and then we will talk.
