Lydia DePillis speaks for all of us in Sunil Gulati’s Global Economy class when she reports an inability to concentrate on Nobel Prize winner Robert Mundell’s guest lecture today because of his eerie resemblance to Donald Trump. Mundell’s photo doesn’t quite do the parallel full justice; it’s pre-awful auburn hair dye job.

What Mundell didn’t mention in his lecture was the fact that he’s a frequent guest on the Letterman show, mainly for his deadpan delivery of top ten lists, excerpts from Paris Hilton’s memoir, “You might be a redneck lines”, and Yo Mama jokes.
