Hey lets ban squirt guns on campus too.
Banned:

Not banned:

I would love to see them try to expel me for a squirt gun.... technically its in their bi-laws -- "harmless instrumentality designed to look like a firearm" -- But I would sue their coffers dry.
I do think that if I were a student there, I would keep playing the same zombie game, but with Nerf Footballs...... Force their hand and make them outlaw footballs on a college campus... that would be great!
