Double Your Shopping Pleasure

I know they're already like billionaire entrepreneurs at the age of 21, but doesn't it seem like the only thing the Olsens ever do is shop? (Yeah, yeah, I know Mary-Kate's doing a guest-starring thing on Weeds, but what was that, one day's work?) I guess having been working since they were infants gives them the right to slack off in their 20s, but wouldn't it be cool if one of them, in a sudden quarter-life-crisis, decided to do something crazy like become a pharmaceutical sales rep?
