Haha, Jenny thats funny, we used to do it too, brother used to go on forever. One day though the fence run up against the back of the shed, and he decided it would be a good idea to reach for the steel girder at the corner of it ha, litteraly launched his hand off it with the biggest crack! He never did it again.
I am doing lasser though, I am normaly very pain resistant, but it just make you jump, not really painfull, just always feels like a suprise haha
