Last night's episode of "Saturday Night Live" featured musical guest Eminem, who brought out Rick Rubin to help out with his Marshall Mathers LP2 single "Berzerk". As a lot of people on the internet are quick to point out, it looks like he was lip-syncing. Later, he did "Survival" with Skylar Grey. Watch both performances below via Mr. World Premiere.
