There are a lot of people who would like to sock Martin Shkreli in the kisser, and now someone will get the chance.

The former pharmaceutical company CEO, who outraged millions by raising the price of an AIDS drug more than 5000%, is auctioning off the chance to punch him in the face for charity.

Shkreli went on Twitter Monday and announced one lucky (and wealthy) bidder could pay to punch or slap him in the face, with proceeds benefiting the family of Mike Kulich, his recently deceased PR rep.

Kulich, 29, died suddenly last week, leaving behind a fiancé and a young son who survived cancer.

Shkreli says he's already received bids for $25,500 and $78,000.

In December, the former head of Turing Pharmaceuticals, was arrested on securities fraud charges. His trial has been set for June 26, 2017.
