Dress like Lewis from the movie Revenge of the Nerds. Don’t forget the glasses and the pocket protector, rip the seem of your pants along your butt crack and were the fake but thing. Glue some toilet paper in the crack and walk like you’ve got the worst itch of your life. If you can find a good pair of fake buck-teeth, wear them as-well. (talk with a small yet noticeable stutter, and “accidentally” brush your fake butt on the leg of your boss as he/she walks past.
