John Oliver reveals how he used to troll Last Week Tonight neighbor Dr. Oz

TheWrap

Oliver mocked Mehmet Oz's campaign for Pennsylvania's U.S. Senate seat, pointing out how Oz lives in New Jersey. “When he wasn’t in New Jersey, he was often here in New York," said Oliver. "And the reason I know that is his show filmed in this studio. His offices were actually right across the hall from us.” Oliver then revealed that he and his team have been trolling Oz for years with a giant alligator prop holding up its middle finger in the reception area.
