Eminem taught Jimmy Kimmel how to write, compose and rap. The track’s name is briefcase Joe. Eminem advised Jimmy to get an idea from his past and he came up with one about his dad’s old briefcase and how guys in junior high school nick named him as briefcase Joe, hence the name of the track.
One of the funny parts is when Jimmy says” This one goes out to all my hommies in Compton,” and Em stops and the beat and asks him if he knows anyone there.
