Once Upon a Time in Shaolin​ owner Martin Shkreli recorded a video dissing Ghostface Killah and threatening to erase his contributions from the one-of-a-kind Wu-Tang Clan album. In the video obtained by TMZ, the notorious pharmaceutical executive stares directly at the camera in a room surrounded by masked men.

He addresses Ghostface by his given name—Dennis—and threatens to remove him from Shaolin and the "record books of rap" as he calmly sips from a glass. "You're an old man—an old man that's lost his relevance, and you're trying to claim the spotlight from my spotlight. That's not going to work, Ghost—Dennis. In fact, I think that if you ever say some dumb shit again, this album, this Shaolin, I'm going to erase all your shit from this album. I'm going to erase you from the record books."

"You're going to be done. You have to listen to me. I butter your bread, do you understand me?" He continues, "Ghost, stop pretending, stop acting, stop lying. Be real, as your video once said, and uh, don't ever fucking mention my name again, or there will be more of a price to pay than just this video." If you remember, Ghostface previously shared some strong feelings he had about the owner of Wu-Tang's album. Meanwhile, Shkreli is currently awaiting trial on charges of fraud. Watch the ridiculous video above.

A @GhostfaceKillah response tomorrow evening. Don't cry, Ghost. All rap careers come to an eventual end. Long time coming, motherfucker.

As mentioned in my video, I expect a written apology, @GhostfaceKillah. At least 500 words, no grammatical errors and Shaolin stays intact.
