Pimpin' ain't easy, but it's necessary: Ice Cube said it, but when Joel Goodsen had to pony up for Princeton, it was time for the young buck to live it. And when it comes to peddling flesh, what shields a young entrepreneur's eyes better than the most versatile (and morally flexible) sunglasses ever? Ray-Bans, like spray tans, tilted brims, and the cautionary backhands, will never go out of style. Well, except the last one. Please don't slap your girl. Thanks.
