I've been kicked, punched, slapped, kneed, elbowed, stepped on, hit with a drumstick(not the chicken kind), flicked, had a belt strap nearly kill me on one of those slingshot rides, hit with a plastic shovel, had darts thrown at them, had a baseball dropped on them, I've had small children that merely wanted a hug damn near cripple me with a headbutt to the crotch... ANd I'm sure I've forgotten or blocked out more examples. Just a couple of weeks ago I nearly hit the ground, when a girl I was walking with tripped & grabbed for me, well she grabbed for my balls, thankfully she didn't squeeze.
I promise you I am not one of those idiots on the net that does this stuff on purpose, all of those have been accidents or someone else wishing me harm. I'll be amazed if I ever have kids at this point.
