Your job is to match each switch to it's bulb. You may only enter the room once, and you may not leave the door open. How do you accomplish your task? [/b]

I posed this question to my roommate.
His quick response was: "That'd be really easy! You rig up a servo and attach it to a computer and program it to turn the lights on one by one. It turns on one light at the beginning, at ten seconds it turns on a second light, and at twenty seconds it turns on the third light."
Riddle me this: what is his occupation?
