hehe, i screwed up. Trialing the new mail server at work and the comms team haven't set it to recieve thru the f/wall yet. changed my details and the UBB was meant to auto send a new password to my new address. "BOUNCE!" So I made a new account without a space in the name. Enter the 'Lamor' rating from stage left.Hey it feels good to be humble again.
Back to the task, silkwrap him a copy of BO2K and do stuff to his registry. Pull his PWL file and his Internet acct details and screw with his account. Nothing that will last but a rebuild/install is always unwelcome.
As for the car, the coolest is to write on his hood with lipstick - you need industrial solvent to remove it. Or pour brake fluid on his paint - bye bye. Best one I heard though, was an slightly opened can of sardines under the back seat or inside the door panel.
