Martin Shkreli is known for raising the price of the HIV/AIDS drug Daraprim and for trolling Hip Hop by buying famous rap albums and sticking them in his personal vault.
Karma hit him in the face last night during an appearance at UC Davis in California.
That was a bag of dog poop that hit him right in the mug.
"Piece of shit" somebody yelled before he did.It's been a tough stretch for Shkreli; last week he was banned from Twitter for harassing a female journalist.
