we had a vice principal that no one liked because he was always finding ways to give us detention, so we went through the mall one saturday and signed him up for every sweepstakes, free offer, etc. and gave the schools number and address for a contact. He could never prove it, but he one day asked me why he would be getting 5 calls a day about winning timeshares and aluminum siding....I told him it was because he was a very lucky person and he deserved it for his hard work 🙂
on a side note, we also stole a realitors "for sale" sign and put it up in his yard when everyone had gone to bed.....it was super funny at the time, but i guess these things die with age
