He does diss Eminem some in a song called Curriculem 101
Anybody better than Bis must be a hoax
Black man, no, what about the great white hope
What? you must be sniffin great white coke
Dont you know thats like Gary Coleman fightin the hulk
Still not even that quite that close
A great white biting your rubber dingy boat 50 miles off coast
What the fuck is the mathers with you?
And he goes on a little bit.....its pretty tight
