Cactus Hacky Sack [VIDEO]

Three friends, one cactus, one camera= Entertaining yet painful video. This guy got the bright idea to flick a piece of cactus that was stuck on his shoe at his friend. I am not so sure why he sounded so surprised that it stuck to him like a velcro dart. If this happened to me I am not so sure I would have been so calm. I would have either A) screamed like a little girl or B) been gotten really pissed off. I have been stuck by a cactus before, no bueno.

How would you react?
