Jack McBrayer, better known as Kenneth the Page from '30 Rock,' visited 'The Tonight Show with Conan O'Brien' to discuss his recent Emmy nomination and his maniacal smile.
"This is not just a pleasant smile, this is a nuclear powered smile," Conan said. "It's crazy. If someone broke into your home, would you just be smiling at them?"
"Yeah to disarm the situation," Jack joked. "Hi, let me get you some lemonade."
He went on to do an impression of his '30 Rock' costar Alec Baldwin and talk about his Southern parents' first meeting with another costar and fellow Emmy nominee, crazed comedian Tracy Morgan.WATCH:
