That's on par with having a bunch of pizzas delivered to your enemy's house. I know someone who filled out one of those cards where you adopt a child in Mexico for someone he was pissed at. Several enemies, including nasty teachers, were later harrassed by some shrewish hard sell World Book lady. Whenever I go to see a band, I sign up coworkers that I don't like for the band's mailing list. Guess What! Poor Deena.

We don't like unsolicited junk mail any more than you do. It sounds like she's in a really bad place. This also puts you on our mailing list to stay informed of future trips, unless you request otherwise. I found a mail-in card for problem bedwetting and filled it out in the name of someone who had pissed me off.
