The Older I get the Less I Can Stand Teenagers!

I am about to turn 28, and I really don't like tolerating any teenagers or guys in their early 20's. The are so damn lazy, know everything without knowing anything, and want you to do everything for them, and get ****** if you try to teach them something you learned from experience. I just wish I had a "get out of jail free" card so that the next time at work one of these little sob's bows up to me, I can knock their scrawny little heads off and let them feel what 260lbs of fist up their head really feels like so they will no longer be disillusioned. Im normally laid back, and have no ego or mancard that will provoke me into making a scene. Not much you can say or do will make me that mad, but these littles ##*$*$* do it enough repeadedly to make me say they have crossed a line and someone is going to be made example of.
