"This whole trip to Scotland, I can't tell you how lovely it is. How great the people are, how beautiful the towns are. I'm shocked … my memory is completely wrong," Ferguson told guest Rashida Jones while filming in Arbroath Harbour.
Other stars to appear on the special editions of the late-night chat program are actress Mila Kunis, actor Michael Clarke Duncan, author David Sedaris and "Flying Wild Alaska" star Ariel Tweto.
Throughout the week, Ferguson will be seen exploring Edinburgh, Glasgow and his hometown of Cumbernauld. Along the way, he also visits Edinburgh Castle, The Royal Mile, Calton Hill, Glamis Castle and Kelvingrove Art Gallery, as well as his childhood home and high school, among other locations.
