Former price-gouging pharmaceutical company CEO Martin Shkreli asserted his Fifth Amendment right against self-incrimination at a congressional hearing Thursday, but still managed to conduct himself like a professional douchebag for the world to see. Check out the video below.

Shkreli, who was arrested in December on securities fraud charges, made himself infamous by dramatically hiking the price of a previously inexpensive antiparasitic drug often used to treat HIV patients.

Shkreli has also been writing checks that his ass can’t cash by making serious threats via social media to Ghostface Killah, RZA and the rest of the Wu Tang Clan after purchasing their Once Upon A Time In Shaolin album for $2 million last year.
