I would think Kanye's in the same boat as Linkin Park: If Al were to parody him, he'd have done it by now.
Only difference is, Linkin Park is still (Surprisingly IMO) topping charts and Kanye is doing desperate things to keep his career going like posing r&b as rap to appeal to a wider audience and win the big awards he so humorously keeps getting shut out of (Boy, I never thought U2's How to Dismantle an Atomic Bomb was Album of the Year worthy, but damn that one was funny....if their latest "Masterpiece"

beats Kanye, I'll laugh for days)
Brandon has gotten so big......
