Find a teacher willing to accept bribes. I.E. some of the really desperate ones, I'd go after pisciotta because he is just grungy like that (needs money for weed). Offer him three dollars per note that he writes that would get kids out of class. Say. "Excuse Max third hour he is doing a test in my class" Sell these notes to kids for 7-20 dollars depending on how long they want out of class. Let me run that back to you.
1. Offer bribe to teacher
2. Teacher writes notes, get kids out of class.
