Last night was a packed couch, with David Walliams, Annie Lennox, Shirley Bassey, Richard Ayoade and Catherine Tate.
However, the real stars of the show were the people on the Red Chair.
One featured a skin transplant, one was about a mermaid (yes, really) and another was... well, you'll see.
Honestly, could you imagine this kind of thing going down on the Late Late? Speaking of which, we'll have highlights from Norton on the Late Late Show a little later on.
Try saying that very quickly.
Take a look!
