just do the crip walk when you leave and don't forget to cross your eyes, have drool running down your chin and have your upper torso tilt the opposite direction of your lower torso. to add realism, emit a low droning gurgling noise and stick a finger up your nose. most importantly, smear a touch of dooky on your forehead and leave your pants and tighty-whiteys down at your ankles as you make your way past any uppity-self righteous handycappers. just a suggestion. worked for me once.
