stupid trick,, is to give an unsuspecting friend a rifle or hand gun that is greatly out or their league, ones that recoil far more than anything they are used. Like giving them the key to a race bike when they have never ridden a bike that powerful , just to entertain as they may possibly get hurt. Like giving a 10 gauge to a 10 year old and laughing as he fires it. Hoperfuly it was a over charge. No injury intended.
