saturday night live

As we've seen in the past, you never know who's going to make an appearance during a "Saturday Night Live" monologue. Case in point: host Seth Rogen found himself joined by Taylor Swift, Zooey Deschanel and James Franco. Watch it here.

Seth Rogen hosts this week's "Saturday Night Live" with musical guest Ed Sheeran, and he's joined by castmember Aidy Bryant in these promos, which include a painfully awkward attempt at improv.

There were plenty of high points on last week's "Saturday Night Live" hosted by Anna Kendrick, but somehow this Nickelodeon sketch failed to make the cut after dress rehearsal. (Trivia: This sketch includes "SNL" castmember Kenan Thompson, who starred on Nickelodeon's "All That"...

Anna Kendrick hosted a song-packed episode of "Saturday Night Live" where it seemed that she sang in just about every other sketch, but the one that stands out in our minds the most is when she deviated from her good-girl image to perform an ode to "Dongs All Over the World", featuring a cameo from Swedish pop duo Icona Pop...

This was one of the unquestioned highlights of this week's "Saturday Night Live" with host Louis C.K., who took part in the best sketch of this week's episode, "Black Jeopardy". (P.S.: I got all the answers right!)  

Louis C.K. makes his second appearance as host of "Saturday Night Live" this week with musical guest Sam Smith. Check out these promos with "SNL" castmember Kenan Thompson and hope he does something as awesome as "Lincoln" this week.

Louis C.K. will return as host of "Saturday Night Live" March 29, according to an announcement made on Saturday's episode.

"Girls" star Lena Dunham hosts "Saturday Night Live" this week with musical guests The National, and in these promos, Lena and castmember Kate McKinnon make things hilariously awkward for each other.

Jim Parsons of "The Big Bang Theory" made his hosting debut on a somewhat lackluster 'Saturday Night Live", and the highlight of the show was the introduction of Tinker Bell's half-sister, "Tonker Bell", played by Aidy Bryant. Get ready to get TONKED...

"Big Bang Theory" star Jim Parsons makes his hosting debut this week on "Saturday Night Live" with musical guest Beck. In these promos, Jim and castmember Bobby Moynihan try to out-prank each other (Bazinga!) and show off some sweet Olympic moves...

'Girls' power! Lena Dunham, star and creator of 'Girls,' has nabbed her first 'Saturday Night Live' hosting gig.

NBC announced Thursday that "The Big Bang Theory" star Jim Parsons will host "Saturday Night Live" when it returns March 1.
