Greg Mankiw endorses Vampire Weekend, calling them "the best new rock band [he] has heard in a long time." If you don't know Greg Mankiw, he's the square who probably wrote your Microeconomics textbook, if you were dorky enough to even take that class.
And since I'm such a big square as to be reading his blog, I will do you all a huge favor and never endorse your band. In fact, if you'd like I'll criticize your band, which will probably improve your standing via the Conformity Theory. Let me know.
