Shkreli appears in a new video surrounded by three masked men (via TMZ). Using Ghostface Killah's real name, Dennis Coles, Shkreli launches into a lengthy rant. 'Most people don't ever try to beef with me, know why?" he arrogantly asks the camera. 'Because nobody's that dumb."

He continues, "For whatever reason you think it's okay to beef with me, but that's a big mistake. At the end of the day, I feel very sorry for you. You're an old man who has lost relevance and you're trying to reclaim the spotlight from my spotlight. And that's not going to work, Dennis."

"In fact, if you ever say some dumb sh-t again, this Shaolin album, I'm going to erase all your s- on this album," he says. "I'm going to erase you from the record books of rap. You're my son, you have to listen to me. I butter your bread, you understand me. Without me, you're nothing. I expect you to write me a written apology from the heart. Some contrition, some long letter where you explain you're sadness and sorrow for what you've done."
