Yeah, I'm fond of the thought of putting someone else's house up for sale, myself. There's probably some stupid law against doing that, though.
I never heard from anyone about the stapled shut mail box, so I think that one is just going to be our little secret.
As far as stupid deeds from my mis-spent youth, I'd say that driving over Red Mountain Pass with a pint of Wild Turkey in the middle of a raging blizzard was right up there. On the way, I over took a snow plow driver who got slicked off the mountain by an avalanche about 20 minutes after I'd passed him.
