When comedian and author Craig Ferguson stops by, Rachael congratulates him on passing the 500th episode mark of the Late Late Show, and asks if he has any advice for her as a talkshow host. "When I started, I asked my boss, David Letterman, what do I do?" Craig remembers, "He said, 'It'll come to you, just keep talking. Whatever you do, just keep talking.' So I think you're going to be OK!"

Rachael tells Craig that she's going to be visiting his home country of Scotland this summer. Does he have any food advice for her? "Yeah, England would be a good place to go!" he jokes.

Craig has Rachael in stitches when he joins her in a game of Stump the Rach!

"I'm a confident man!"
