Based on his "Conan O'Brien Needs a Fan" podcast (a spin-off from "Conan O'Brien Needs a Friend"), "Conan O'Brien Must Go" sees the veteran comedian meet his fans in Norway, Thailand, Argentina, and Ireland.
If you love Conan, you'll know what to expect: lots of silliness and lots of Conan happily acting like a clown for various people.
Full credit to Conan though, he's up for anything: singing multiple times (including singing on a Thailand reality/talent show), going indoor rock climbing, trying spicy street food, making a cameo on an Irish soap opera, starring in an animated short film, learning how to be a viking, learning to knit, playing soccer in Argentina, and learning Muay Thai boxing. He fully immerses himself in every stunt.
While some of his fans are overwhelmed when they see him, Conan manages to bond with them (and their families) and find a connection: he genuinely cares about his fans.
There's also a guest appearance from Conan's long-time co-worker Jordan Schlansky. Jordan is so straight-laced and 'cultured' that it's hard to tell if he's a genuine snob or if it's all act to wind up Conan. In the Argentina episode, Conan and Jordan (jokingly) argue about the correct pronunciation of 'tango'.
The Irish episode is the best, as Conan not only visits his fans, but tries to learn the language and learn his family tree from a genealogist. Watching Conan discover more about his great-grandfather is the closest the series gets to a serious moment, as you can tell Conan's heritage means a lot to him.
If you're familiar with Conan's podcasts, then you'll love these specials. There's lots of cameos from co-hosts Sona Movsesian and Matt Gourley in the podcast interview segments and a special opening titles narrator that "Needs a Friend" fans will love.
