This week, Jimmy Fallon helped Britney Spears sign up for Tinder, and also participated in a Tonight Show edition of Family Feud that went completely off the rails. Former Saturday Night Live cast member Bill Hader shared a hilarious Casey Kasem sketch that tragically never made it to air, and Ellen DeGeneres released her own version of Nicki Minaj's "Anaconda" video. Elsewhere, viewers also got their first taste of Utopia and its amazing theme song, as well as a very special Jeff Goldblum rendition of the Jurassic Park theme song. Check out those clips and more in our weekly roundup of the best online videos:
Jeff Goldblum's Jurassic Park theme: Who doesn't love the Jurassic Park theme song? Jeff Goldblum leads the Late Night audience in a sing-along to a version of the tune — with lyrics!
Bill Hader's Casey Kasem sketch: Words can't express how disappointed we are that this hilarious-sounding sketch about Casey Kasem and his son "Jasey Kasem," written by Bill Hader and John Mulaney, never made it past dress rehearsals on Saturday Night Live.
DuckTales intro with actual ducks: Viewers of a certain age will get a healthy dose of nostalgia upon hearing the theme song to DuckTales, the beloved Disney Channel cartoon from the late 1980s. What could make it better? Replacing the cartoons of Huey, Dewey and Louie with actual ducks.
Utopia theme song: Is Daughtry's theme song for Fox's new reality show Utopia amazing or amazingly bad? We're leaning towards the latter, but we can't stop listening anyway.
Britney Spears signs up for Tinder: In the latest instance of "Celebrities, they're just like us," Britney Spears gets into the online dating game and signs up for a Tinder profile — with a little help from Jimmy Fallon.
Tonight Show Family Feud: Also on The Tonight Show this week, Steve Harvey hosted a special edition of Family Feud, pitting the Fallon Family (Jimmy Fallon, Jason Segel and Steve Higgins) against the Roots family (Questlove, Tarik Trotter and James Poyser). The result may be the most disastrous Family Feud competition ever.
Ellen's "Anaconda" video: Why should Nicki Minaj have all the fun? Ellen DeGeneres gets in on the "Anaconda" game, showing she can twerk just as well as Minaj does in her latest video.
