Sly was horrible, and that tribute fell very flat (other than the cuntry crap, by far the worst performance of the show). If I had to guess I'd say Senor Stone has ingested thousands of hits of ecstasy - it was like his neck was fused together and he couldn't rotate his head around. His mic was super low to where one could barely discern his voice, and then he walked off the stage before the song was over.  

So let's enjoy
Let the X destroy your spinal cord
So it's not a straight line no more
'Til we walk around looking like some wind-up dolls
Shit's sticking out of our backs like a dinosaur
Shit, six hits won't even get me high no more
So bye for now
I'm going to try to find some more
-Eminem, Drug Ballad
