Ep 20. Zac Efron/Yeah Yeah Yeahs

Zac Efron, heartthrob actor of High School Musical fame, hosted the 20th episode of season 34 of Saturday Night Live. The musical guest was the indie rock band Yeah Yeah Yeahs.

The episode kicked off with a sketch parodying President Obama's first 100 days in office. Fred Armisen reprised his impression of Obama, joking about the challenges he faced and the accomplishments he made in his first few months as president.

One memorable sketch from the episode was a fake commercial for a product called "Cool Shoes." Efron played a customer who is excited to try out the shoes, only to find out that they are completely impractical and uncomfortable. The sketch featured some physical comedy as the cast members tried to navigate the clunky shoes on the set.

Another standout sketch was a parody of High School Musical, the franchise that made Efron a household name. In the parody, Efron played a washed-up former star of the franchise who is struggling to find work. The sketch featured some self-referential jokes about Efron's career trajectory and ended with a musical number that poked fun at the original movie's formulaic songs.

The weekend update segment featured some of the show's regulars, including Seth Meyers and Amy Poehler. The segment covered the week's news, including the swine flu outbreak and the controversy over torture memos from the Bush administration. The highlight of the segment was a guest appearance by former SNL cast member Will Ferrell, who came on to promote his new movie, Land of the Lost.

The musical guest for the episode, Yeah Yeah Yeahs, performed two songs: "Zero" and "Heads Will Roll." The band's energetic performance was well-received by the audience and provided a nice change of pace from the show's comedy sketches.

Overall, Zac Efron's hosting gig on Saturday Night Live was a solid episode with plenty of laughs. The sketches capitalized on Efron's good looks and likable personality, while also poking fun at his somewhat limited range as an actor. The Yeah Yeah Yeahs' musical performances added some extra excitement to the episode and showed that SNL can still attract cool and current musical guests.
