The broadcaster appeared on Conan on Wednesday night, and while accepting praise for his job hosting the coverage of London 2012, he took a shot at the network's decision to interrupt the broadcast of the closing ceremonies to air one of its new comedy pilots.

"NBC decides at that moment, they should provide America with a sneak preview of Animal Practice, and then come back an hour later and check in on The Who," he said. "Animal practice is evidently a comedy, or at least we're hoping it is, that revolves around a veterinary practice, and one of the doctors is a chimpanzee."

NBC was mocked for the decision, as well as its practice of tape delaying events to play them during primetime, but that didn't stop it from earning record ratings during its two week run.

Still, Costas couldn't help tredging up a little more NBC controversy, nodding at the Tonight Show saga that saw Conan O'Brien replaced by a returning Jay Leno.

"I'm sure you'd be the first to attest, Conan, when it comes to the tough calls, NBC usually gets them right," he said, prompting O'Brien to call him "the best guest ever."
