Martin Shkreli — the former Turing Pharmaceuticals CEO who gained notoriety for raising the price of an AIDS drug more than 50-fold — is now auctioning off the opportunity to punch him in the face for charity. The man took to Twitter Monday to announce that he would grant the highest bidder one chance to punch or slap him in the face to benefit the family of his recently deceased PR consultant Mike Kulich, who died in his sleep Saturday morning.
