President Obama will make his first appearance on Jimmy Fallon’s late-night show when he appears Tuesday in a taped segment from the University of North Carolina. He is expected to discuss student-loan costs, which certainly fits with Fallon’s demo better than Leno or Letterman. Hopefully his segment will go better than Michele Bachmann’s guest appearance on the show in November, when house band The Roots performed the 1985 Fishbone song “Lyin’ Ass Bitch” as she walked onstage. Fallon and NBC were forced to apologize.
