Watch Ellen DeGeneres Join Sean Hayes and Kristin Chenoweth Onstage in Promises, Promises

Earlier this month, Emmy-winning comedian Ellen DeGeneres surprised audiences at the Broadway Theatre when she showed up for a cameo in Promises, Promises as Consolidated Life Insurance's new office nurse. DeGeneres greeted the show's star (and her old friend) Sean Hayes as his character heads down to the medical wing to have a cold checked out...and DeGeneres' comic timing is just what the doctor ordered! For her Broadway "debut," the funny lady improvised a bit by trying out a hilarious, elongated and hauty accent that promped Hayes to crack, "You sound like a ghost!" DeGeneres then reappeared in a scene featuring Kristin Chenoweth where a brief line flub caused the comedic threesome to crack up. Check out the clip below. We promise you'll love it!
