Sir Mix-A-Lot will be knighted, and he will be Sir Sir Mix-A-Lot. Trust us on this. It's going to happen. We're pretty sure Nostradamus predicted it and everything. When that glorious day comes, we will use this site to keep the world informed of SSM's knightly deeds. News of every dragon slain, every castle stormed, and every big-bootied princess rescued will show up here first. In the meantime, here's a video from Robot Chicken.
Oh, and one other thing: We haven't actually seen the Glee version, but we're pretty sure Jonathan Coulton's right.
Update: Upon listening to the side-by-side comparison, we definitely agree with Coulton.
