I'll bludgeon you wiff it

This comic is mocking how stupid my school system really is. Here's the story.
I was asleep in woodshop class (he's switching rooms so we're not doing anything really) and my friend came up and slammed his hand down on my desk to scare me only his arm got a little close and his spike bracelet connected with my fingernail breaking through it and breaking the skin underneath. Now... remember that. it went THROUGH my nail. I go up to the office with my towel (Hitchhiker's Guide to the Galaxy RULES!) to request a bandage and they stop my speaking to tell me that I can't have a towel on school property because "It's a weapon." I explained the whole story about the METAL SPIKE going THROUGH my nail and they say "Oh. Okay, well, here's a bandage" and hand me one. EXCUSE ME!?! Did I miss something here? Since when is a TOWEL more dangerous than a METAL SPIKE? *shrugs* thank goodness I'm graduating from that insane asylum in two weeks.
