Comedian Zach Galifianakis hosted “Saturday Night Live” on Saturday and brought his typical brand of awkward humor to the sketch comedy show.

One sketch had “The Hangover” actor dress up as a dragon for “Game of Game of Thrones.” It featured Galifianakis playing Duncan, with Bill Hader playing host O.J. Samson. The game is set up is similar to “Jeopardy,” where three contestants answer trivia questions related to “Game of Thrones.” The other two contestants answer each question with plenty of backstory and detail, while Galifiankais chimes in with a bad joke.

When it comes time for Galifianakis to choose a category, he mispronounces “geography,” and, instead of a “Game of Thrones” question, Samson asks Duncan a question about United States geography. Duncan’s bad luck continues as a question about the Lannister family turns out to be a question about a Roth IRA. During the “wildfire round” to end the game show, Duncan continues to get questions unrelated to “Game of Thrones,” but that all seems to change when the contestants are treated to a surprise cameo appearance by “Game of Thrones” star Nikolaj Coster-Waldau.

Duncan goes into a long-winded monologue about being Coster-Waldau’s best friend. Then, Coster-Waldau asks Duncan to identify someone unrelated to the show, holding up a photograph of Supreme Court Justice Ruth Bader Ginsberg

Galifianakis’ awkwardness is a highlight in several other “SNL” sketches in which the comedian can set up seemingly unrelated jokes into a series of awkward silences followed by laughter.

Galifianakis dresses up as a red M&M during a sketch that features Fred Armisen and Jason Sudeikis. As a greeter for the M&M Store, Galifianakis says inappropriate and racist things to his fellow employees.

In a sketch called “Darrell’s House” Galifianakis plays a neurotic host setting up a public cable access show that promises to feature “Mad Man” star Jon Hamm. This pays off at the end of the show with an "edited" version of the segment.
