Yeah, Eminem can rap really fast… But do you think that there’s someone that can sign as fast as Slim Shady?
Actually, there is. Holly Maniatty, the sign language interpreter at Eminem’s set at the Firefly Music Festival can sign just as fast as the rapper – and there’s no more proof than watching this clip of Holly signing to the “supersonic rap” that Em does during “Rap God.”
Watch, and prepare to have your mind blown!
