Christina Applegate celebrated her first hosting gig on Saturday Night Live in nearly two decades through her singing chops, “Californian” attitude and surprise guest Usain Bolt.

Applegate, 40, opened the show with a musical number celebrating the current holiday-free season.

“This is my favorite time of year because there are no holidays yet. No decorations. No cards. No weird family tension. And not every single thing tastes like pumpkin! Just one last glorious weekend when no one’s celebrating anything,” she said, before breaking out into song with some SNL players.

Meanwhile, Bolt received a very warm welcome during the episode’s cold opening, a re-creation of this week’s vice presidential debate, when Paul Ryan (played by Taran Killam) mentioned he won the 100 meter dash at the London games this summer.

What were some other highlights from Saturday’s episode?

The hilarious “Californians” soap opera sketch returned with a bang, as Applegate played Brie, Stuart’s (Fred Armisen) bride-to-be with several secrets up her sleeves.

“I have a shopping addiction, you wouldn’t understand . . . it was so hard, growing up in the Long Beach area,” Applegate said with the familiar “Californians” accent.

Bolt returned for a second cameo near the end of the sketch, playing a Californian looking for his biological father. (He sprinted to the house, of course).

Applegate and the SNL gang also shot a parody trailer of Liam Neeson’s current release, Taken 2, combined with practically all the recent films of that genre.

“If you like the kidnapping revenge part of ‘Taken,’ and the arbitrary group dynamic of ‘The Expendables,’ then get ready for all your favorite revenge movie action stars combining forces in ‘Give Us All Our Daughters Back,’” the voiceover says in the trailer.

In the clip, Applegate plays Uma Thurman’s Beatrix Kiddo from Kill Bill.

“You’ll recognize me. I’m dressed like at taxi,” Applegate says on the phone.

Meanwhile newcomer Kate McKinnon is quickly rising to the top of the SNL food chain. After her effortless portrayal of Ann Romney a few weeks back, McKinnon gave her best Arianna Huffington and Martha Raddatz impressions on Saturday’s episode.

Next up on SNL: Bruno Mars doing double duty as host and musical guest on Oct. 20.

Sunday night’s competition at the 2012 London Olympics included results that were both expected and surprising.

Perhaps most surprising was McKayla Maroney’s disappointing performance in the Women’s Individual Vault finals, in which the 16-year-old favorite stumbled on her second routine to finish second.

Also surprising was the Gold medal final in men’s tennis, in which Andy Murray upset Roger Federer just one month the finals at Wimbledon didn’t go his way.

What else went down on Sunday?

Check out Celebuzz’s full Olympics rundown, below:

1.) McKayla Maroney Stumbles to Silver
In a rare moment, American gymnast and heavy favorite McKayla Maroney fell on one of two routines to finish second in the Individual Vault finals. Sandra Raluca Izbasa of Romania finished in first.

2.) Andy Murray Beats Roger Federer
About a month after losing to Roger Federer in the Wimbledon finals, Andy Murray finally triumphed over the Gold medal favorite, 6-2, 6-1, 6-4.

3.) Serena Williams Wins Gold — Twice!
Tennis legend Serena Williams will take two Gold medals back with her to the United States, one for the Women’s Singles final, in which she beat Maria Sharapova 6-0, 6-1, and one for the Women’s Doubles final, in which she and sister Venus defeated Andrea Hlavackova and Lucie Hradecka of the Czech Republic 6-4, 6-4.

4.) Usain Bolt Remains World’s Fastest Man
As expected, Usain Bolt of Jamaica dominated the Men’s 100-meter final on Sunday, taking the Gold with a time of 9.63 seconds. Yohan Blake of Jamaica (9.75 seconds) and American Justin Gatlin (9.79 seconds) finished in second and third place, respectively.

5.) Sanya Richards-Ross Stages Major Comeback
