"if my anyone brings anything into the school that has peanuts in it they have to sit at a special table by themselves so the 1 child won't be exposed to any peanuts."

What a great way to keep bullies from stealing someones lunch.

In 7th grade there was this one jerk who would always walk by and grab a handful of fries from my school lunch. One week I came down with Strep throat and after two/three days went back to school. I spit on my fries during lunch before the bully came by and a few of my friends were watching. When he grabbed my fries and ate them I very nicely smiles and chuckled and informed him that I had spit all over my food and was currently getting over strep throat and could still be contagious and sarcastically stated that I sure hope that he doesn't get sick.

From that point on every time we were at lunch I made it a point to spit on my food when he walked by. He never stole my fries again.

lol,
My cousin grabbed a handful of my fries one day. I told him if he did it again I was going to stab him with my steak knife. He didn't listen, and I stuck him in the thigh. (In all fairness, I was only bluffing never really intending to stick him and was as surprised as he was, but the effect was the same, he never grabbed my fries again.)
A bully insisted on looking over my shoulder during tests at school once. I wrote down incorrect answers and changed them after he was done. After his test was graded he said, "You're really stupid, I'm not copying your tests any more."
