Joshua Clover is a UC Davis professor of English and an accomplished professional writer. He also happens to own an amazing t-shirt that says "Who the Fuck Is Mick Jagger?" on it. Clover said he bought it because he didn't understand it. Other awesome shirts include "Piece Now" (with a large picture of a gun), "I (heart) Baile Funk," and "WWCLD?" (What Would Courtney Love Do).
