Richard Deitsch of SI.com has the back story on Eminem’s bizarre appearance during halftime of Saturday’s Notre Dame-Michigan.

Bonnell said Eminem arrived at Michigan’s Big House with a small group in the second quarter, and hung out on an ESPN bus for 10 minutes before ESPN escorted him to a room next to the broadcast booth. Prior to the interview, Bonnell described Eminem as “legitimately nervous doing a live interview.” The rapper spoke with Herbstreit and Musburger before the interview started and told them “How do you guys do live TV week to week?”

Bonnell said what viewers did not immediately recognize was that Eminem took on the persona of his Berzerk character in the video. “He was just messing with everyone,” Bonnell said. “We had no idea he would do that, but if you see the music video, it’s him looking into the camera and doing a throwback to the ’80s. You clearly saw after the video was over, he became Marshall Mathers again. He was goofing around.”
