James Corden stopped by CBS's Late Late Show tonight to kick the tires. It went well. “Are you ready for this?” Ferguson asked Corden. “I think so,” Corden responded hesitantly. “I'm delighted you're taking over, and I'm very very sorry for what's about to happen,” Ferguson said, adding, “You sure you want to do it?” “I think it's too late, Craig — but you're looking good,” Corden observed hopefully. “That's because I'm leaving!” Ferguson joshed.
