I know a guy at work just like you. He just needs a simple touch of the back to send his coffee flying everywhere!!!I REALLY am! Ask my son. His idea of a good time is to hide in the dark and step out and say,"hello" or something equally weird. I then jump and put my head through the drywall, cuss on the way down, get yelled at by my wife for swearing, slug my only child wherever my fist lands, all in the space of 1.4 seconds. I tell my son all the time that he has a stupid hobby but he never listens..... Maybe I should buy him a clown suit and make him join the circus, the brat.
