Letterman also joked in his "Late Show" monologue about the Super Bowl spot. "People really thought this was big-time stuff, so I just want to take a second here now to thank the actors who played Oprah and also Jay Leno," he said. "They did a tremendous job."
Last week, Leno took a day off from his show to fly to New York to make the 15-second commercial. Leno was driven to Letterman's studio in an SUV and even wore a disguise.
