Why did Sue Sylvester’s mom leave Ohio? Well, based on this duet from Tuesday’s episode of Glee, it might not have everything to do with hunting Nazis, as Sue once claimed. And it’s too bad Sylvestor Senior (played by comedy legend Carol Burnett) skipped town — the duo seem to pair together in perfect harmony. No, really: The vaudeville-esque “Ohio” from the 1953 musical Wonderful Town showcases both their wonderful voices — and makes you wonder why Sue doesn’t ditch the tater tot talk for more singing.
