Even 100 couldn't do it unless he let them. If he picks one of them up and rips their arms off, the rest of them run away screaming.
200 or 300 piled on top of him and that's enough weight that he couldn't move. Obviously the first 50 or so would die but then he would start falling over bodies....
send one with a runny nose in early....then wait a day or two until Shaq is down with the flu and headache. 40-50 should do the trick then. any sane person would wave the white flag seeing a busload of 1st graders storming the gate while you are sick.
