What to Watch this Weekend: Jimmy Fallon on SNL and the Season Finales of Survivor and Homeland

Now that the sun sets at noon-ish, the brightest light in our lives is that bluish square we keep in the living room. Here are the items it'll be flickering at us this weekend:

What to watch on Friday, December 16...

8pm, NBC
Chuck
In "Chuck Versus the Curse," Chuck and his favorite galpal Sarah race to stop a dangerous computer virus while also fighting off the dastardly intentions of a sexy superspy played by Rebecca Romijn. Elsewhere, Ellie and Captain Awesome's date night gets ruined. See, and you thought distractingly attractive people had it easy.

9pm, NBC
Grimm
In "Let Your Hair Down" (which fairytale could that be a reference to?), a missing-person case is reopened after a seemingly related murder occurs. Meanwhile Nick needs a favor from Monroe. Which reminds me, how's your Grimm slashfic coming? Link pls.

SEASON 3 PREMIERE, 9pm, HBO
The Life and Times of Tim
HBO's funniest kinda-animated comedy returns tonight! In the first segment, Tim takes a job assisting a WNBA player and in the second he decides he needs a better haircut for a new job interview. Which I guess is sort of a spoiler about how the first story turns out.

10pm, Syfy
Sanctuary
Will and Magnus find themselves trapped in a cave-in while pursuing an Abnormal in Bolivia. Meanwhile Henry toils away at his newest invention while recording video letters to his special someone. But don't just take my word for it.

What to watch on Saturday, December 17...

11:30pm, NBC
Saturday Night Live
Ladies! Tonight Jimmy Fallon returns to the fold for hosting duties, and he'll bring with him similarly dapper crooner Michael Bublé. More like Happy Hunkidays, am I right? (I don't know if I'm right.)

8pm, Animal Planet
Too Cute! Baby Sloths
Not sure I appreciate the title of this show telling me how to feel, but still: baby sloths! Why not take a trip to a Costa Rican sanctuary dedicated to raising orphaned and/or injured sloths? You have no reason not to.

ORIGINAL MOVIE, 9pm, Syfy
Earth's Final Hours
After a "super-dense fragment of interstellar mass" (um, an asteroid?) pierces the earth's core, the planet basically stops spinning and doomsday starts happening. Tune in to see these horrifying events unfold via special effects that resemble a late-'90s screensaver.

ORIGINAL MOVIE, 8pm, Hallmark
Christmas Comes Home to Canaan
Fans of Billy Ray Cyrus Christmas movies, look no further: Christmas Comes Home to Canaan tells the story of a widower who finds love with his son's physical therapist and invites her to spend Christmas with their family in Canaan. This sequel will most likely answer all the burning questions that 2009's Christmas in Canaan left you with.

What to watch on Sunday, December 18...

SEASON 23 FINALE, 8pm, CBS
Survivor: South Pacific
An alternatingly compelling, maddening, and unsurprising season wraps it up tonight with the classic Survivor jury-grilling and live reunion special. The primary point of interest revolves around what might happen when the ousted Redemption Island inhabitant returns to the game, especially since most of the jury despises the remaining players. But personally, I'm more interested in the preview for next season. You know, the one without returning players dominating newbies.

SEASON 1 FINALE, 10pm, Showtime
Homeland
Forget reality shows about smelly people or long-in-the-tooth serial killer dramas, tonight's main event is this, the 90-minute finale of Homeland. As Carrie's condition deteriorates, Saul attempts to make sense of her timeline. Meanwhile Walker sets up for his primary mission and Brody gets ready for his presumably momentous meeting with the vice president. Merry Stress-mas!

SERIES PREMIERE, 9pm, TLC
Geek Love
No, this is not a companion series to Virgin Diaries. Geek Love is actually a charming reality show about speed dating amongst attendees at New York Comic-Con. Tonight's nerdy single cosplayers include Iron Man, Harry Potter, and Chewbacca.

SEASON 6 FINALE, 9pm, Showtime
Dexter
Tonight Dexter and the other detectives attempt to defeat DDK once and for all. Meanwhile Deb declares war on her own imagination and also we the viewers can hopefully put this whole situation behind us.

ORIGINAL MOVIE, 8pm, Hallmark
Christmas Magic
A "new angel" (a.k.a. a lady who died) must earn her wings by helping a depressed yet attractive widower save his small business. Ugh, being dead sounds like the worst.
