A little after 1 a.m. this past Saturday morning, Martin Shkreli did what he does more or less all the time now: he turned on his computer and began livestreaming on YouTube to his small but feverish fanbase. Normally Shkreli might strum his guitar or engage in inane conversations with his viewers, but this time, at least at first, something was different: a woman was sitting on his lap, and later she would use several needles in an attempt to drain a cyst above his elbow.
