Some of the mid-level attacks include:
GADC’s demonic Mac Scripting: “Make a Shutdown script and save it as an applet with a name that in no way implies its true nature. Then set it up to run on startup or on login. Now whenever the victim starts up or logs into the computer, it’ll shut down. This one is killer for obvious reasons.”
Tim’s Birthday Chair:
Disassemble a musical birthday card and carefully tape it underneath a coworkers chair so that when the chair is leaned back, the card activates. It took more than four hours for one coworker to discover the source of the intermittent noise!
And Brendan’s Word hack:
Subtle in execution, but so hot when it yields results. Change the AutoCorrect on a coworker’s Word settings such that when he types in, say “facilitate,” it gets auto-corrected to “faliatiate”. Don’t have the patience to wait for him to type facilitate? Change “the” to “teet”, and so on.
And the Silver Medal goes to Anthony and his 84 Westfalia van cubicle mod. The van cost $400, but the joy it gives is priceless.
