LK's made some pretty good humor raps back in the days, though they were all covers with different lyrics. Shady did a cover of that one song with YGO lyrics for that YGO movie abridged mash up they did some time back. He seemed pretty good at it though I don't listen to rap much, but not somebody I would listen to on a regular basis
