i'll start by moving to chatsworth, ca to become a pornstar. from there i'll work my way up the porn corporate ladder until i have my own company. while i'm moving up the vagina ladder i'll make friends with the locals, including the bankers. once i have my own company i'll hook some bankers up with some jobs with some top notch pornstars. a little latter down the road i'll ask to do a "bank robbery" photo shoot. i'll remind my banker "pals" of their "success" in the films i hooked them up with and coerce them into getting into this shoot. while they're getting laid, i steal all the cash and replace it with the fake money we had on site for the shoot. everything should go off without a hitch and i'm out to canada the next day.
