Or shout to no one in particular, "George! Show Lenny the way to the rabbits!"
Years ago... I had a big football guy sitting behind me in a college class. Everyone was scared of him because he was such a bully.
One day ...he kept tapping me on the shoulder and insisting I give him my study notes (on the eve of final exams). I tried to ignore him but he wouldn't stop.
I finally stood up, turned around and yelled in his face that if he'd paid attention in class.. he wouldn't need anyone else's notes... and to keep his stinkin' hands off my person. His eyes were saucered and he kept saying..."okay sorry...Okay sorry...Okay".
The professor asked me after class if I'd go visit ALL his classes. *chuckle* Sometimes these goons just need to be called out...and for no one to stand up to them in a very public setting....is insane.
