Following the Olympics, Costas appeared on Conan O'Brien's talk show and jokingly criticized his employer for its decision to air a preview of the upcoming series "Animal Practice" over a performance by The Who during the London closing ceremonies. "So here is the balance NBC has to consider: The Who, 'Animal Practice'. Roger Daltrey, Pete Townshend—monkey in a lab coat. I'm sure you'd be the first to attest, Conan, that when it comes to the tough calls, NBC usually gets 'em right," Costas said, alluding at the end to O'Brien's involvement in the 2010 "Tonight Show" conflict.
