Amen, Sal. I found that the best thing to do is ignore them, because the bullying is usually memtally & emotionally before it becomes physical. If they see they can't break you down, they"ll move on to another target. Of course, if it becomes physical, then you have to stand up to them and very possibly get your ass kicked because they are usually larger than you, or they wouldn't be bullying in the first place. But then, if it comes to that and you have some aggressive friends who go looking for the bully, the bullying will usually stop.
Dean Shapiro had the physical mass that would have served him well as a bully-- and also as a deterant to bullies. It all depended on the eye of the beholder.
