Talk show maven Ellen Degeneres and pop sensation Bruno Mars prank nurse Deborah who is asked to assess Bruno in his dressing room. Bruno wears an earpiece and repeats everything Ellen tells him to say. When Bruno tells Deborah that his throat hurts after attending the Super Bowl, Deborah responds, "What did you do [at the Super Bowl]?" To Bruno's dismay, she has never heard of him.
Ellen tells Bruno to say the following:
"I haven't swallowed since the Super Bowl."
"Why do Pringles come in a tennis ball can?"
"How many throats have you looked at?"
Eventually, Bruno and Ellen let Deborah in on the prank. Watch the video after the break.
