Our congrats to Black Sabbath's Tony Iommi, who has decided to accept the opportunity of being a Visiting Professor at Coventry University in the U.K. The guitar great was previously granted an honorary doctorate by the university, an act that is not uncommon by colleges around the world as they offer to salute those who have achieved great merit in the world.

But Iommi didn't stop at the honorary title, and has already interacted with students at the university and intends to return Coventry this fall to impart his wisdom to other students. Iommi isn't the first rocker to take on teaching, with Bad Religion's frontman Greg Graffin lecturing about life science and paleontology while at UCLA.

With such wisdom being shared, that got us to wondering what other rockers would make great professors. If you were a student, you would hope to get someone who knew a lot about a variety of things and also had a way in imparting their knowledge in a way that you could understand. We'll start with Red Hot Chili Peppers bassist Flea, who opened his own music conservatory in Los Angeles, and there's Rage Against the Machine guitarist Tom Morello who has shown his political prowess over the years, not to mention his knack for public speaking.

Iron Maiden's Bruce Dickinson would make a great professor for an aviation program, and Korn's Jonathan Davis knows his way around the mortuary sciences. Slipknot and Stone Sour's Corey Taylor is a published author, while Anthrax's Scott Ian has delved into the comics world and has hosted TV shows, making him a solid choice for communications or media arts. Speaking of media, who wouldn't want to learn a little more about film from director Rob Zombie or documentarian Dave Grohl?

And while we're at it, how about a pair of rocker's who've led interesting lives with a wealth of knowledge to be shared like Judas Priest's Rob Halford or Lamb of God's Randy Blythe.
