Wear cargo shorts and a Video Game related T-shirt (I'm sure the manager will love your fashion choices, ensuring you the job) Don't take a shower tonight or brush your hair on the morning or do anything else hygiene related.(he might think that you're some kind of fgt that really cares about hygiene, prove him wrong) Stay up ALL night doing stuff, preferably something thatll strain your eyes a lot(he's probably a gamer too so not only will he understand, that'll be so something you have in common, so you'll get the job). Eat a bunch of Doritos and drink a bunch of energy drinks and/or Mountain Dew (make sure you DONT wash your hands though!) Show up ten minutes late (this isnt really a serious job, so why would he want someone who'll take it seriously) BOOM! there you go.
