By request, and because it really is very cool, I bring your attention to Joe Ades who died on Sunday. He sold potato peelers on the street outside the Union Square Greenmarket in NYC. And had an Upper East Side apartment. He was "was a regular at expensive East Side restaurants, where no one believed his answer to the 'So what do you do?' question: 'I sell potato peelers on the street.'"
There's also a great profile of him in (wait for it!) Vanity Fair, thus fulfilling their potato peeler seller profile quote for the century, I imagine. But, you know, there's a lot of money in it, apparently, and an opening now, so if you're looking for work, you might want to consider it.
Here's a quick view of his spiel. Much more on YouTube if you've got a lot of time to kill.
