The world's biggest YouTuber, Felix Kjellberg, (known as Pewdipie online) appeared on Stephen Colbert to discuss breaking the world record for most subscribed by over 15m.
Colbert started the segment with a joke welcoming Felix to television, calling it "a steam-powered medium".
Speaking about Felix's record-breaking forty million subscribers, he "I want to thank the Internet for allowing their emperor to be here today".
Felix, who hails from Sweden, taught Colbert how to swear in Swedish.
Felix explained the meaning of 'Pewdiepie', saying that he lost the password to his original account 'Pewdie' - "which is the sound a laser makes!" - and that he "just added the Pie" for his new account.
"If that's your idea of work, what do you to relax... head to an office for a few hours?"
