Annoyance #23: People who tap you viciously to get your attention!!!

Do you know what really annoys me?  People who try to get your attention my stabbing you horratiously, 
(Is that a word??? No? Screw it, it is now!) 
just to tell you something.  It's like dude I'm right here, I'm not asleep, I sure as hell do not have earphones on.  There's NO freaking reason to have your arm mutilated just to get your attention.  NO ONE IS DYING!!!  Leave my arm alone, simply AND gently TAP my shoulder or arm and tell me what's up.

And that annoys me today...
