No Office Holiday Party
Dec. 17, 8 p.m.
Littlefield, 622 DeGraw St., Brooklyn
$5-$8

Everyone deserves an office holiday party — at least, that’s the idea behind the No Office Holiday Party, which brings together freelancers, contract workers and part-timers who don’t get to have an official end-of-year fete to blow off steam with colleagues. Now in its fifth year, the No Office Holiday Party (a product of The Skint and Brokelyn) is part celebration, part networking event.

Santastical
Dec. 17-24
CSV Cultural and Educational Center, 107 Suffolk St.
$20-$40

This is going to be your most bizarre holiday party this year, no matter how drunk your boss gets at the company’s open bar. Psycho Clan, the artistic team behind Nightmare Haunted House, are putting on “a crazy Midwestern Christmas lawn come to life,” with karaoke, a pretend ice-skating rink and a mistletoe forest. The fun culminates on the lap of one of six twisted Santas (like Bernie Santas or Hanukklaus) for a souvenir photo.

“Oh, Hello”
Through Dec. 20
Cherry Lane Theatre, 38 Commerce St.
$49

You might have seen Nick Kroll and John Mulaney present their crotchety characters Gil Faizon and George St. Geegland on “The Kroll Show,” and now you can see them live in a full-length show called “Oh, Hello.” The wacky Upper West Side retirees will discuss their views on everything from local politics to (of course) the failures of this good-for-nothing generation — including hilarious anecdotes about their own fictional, messed-up families.

“It’s Christmas Time in the City”
Dec. 18-19
Carnegie Hall, 154 W. 57th St.
$40-$122

There are sleighfuls of Christmas concerts coming to the city this week, but the New York Pops offers a special kind of joyous playfulness that few orchestras can match. Their holiday concert features everyone’s favorite seasonal tunes sung by Tony Award nominees Stephanie J. Block (“Wicked”) and Brian D’Arcy James (“Something Rotten”).

“Oh, What Fun! A Philharmonic Holiday”
Dec. 18 & 19, 8 & 2 p.m.
David Geffen Hall, 10 Lincoln Center Plaza
$35-$75

The New York Philharmonic is collaborating with the New York Gay Men’s Choir for a fun mix of holiday classics along with “choralography,” plus a special rendition of “You’re a Mean One, Mr. Grinch” by opera star Eric Owens and a Christmas carol singalong for the whole audience.

“Gilmore Girls” Party
Dec. 18, 9:30 p.m.
Videology Bar & Cinema, 308 Bedford Ave., Brooklyn

Williamsburg’s movie theater-video rental-bar is throwing a “Gilmore Girls” party to celebrate the show’s legacy and share the excitement of its revival.

X-Files Burlesque
Dec. 19, midnight
Joe’s Pub, 425 Lafayette
$15

Like a fever dream you’d have after an alien abduction — or a night of tequila shots — “The Truth Is Out There: X-Files Burlesque” offers a sexy tribute to television’s cult sci-fi show. It’s a naughty night to tide you over until “The X-Files” reboot miniseries kicks off in 2016.

An Evening of True Holiday Tales
Dec. 20, 7-9 p.m.

A surprising number of holiday stories didn’t emerge from the imagination — they’re based on historical events, as with the true tale of the grave robbers of St. Nicholas. On Sunday, historical nonfiction writers Alex Palmer, Bess Lovejoy and Alison Kinney come together at KGB Bar to discuss some of these outlandish holiday hijinks over themed cocktails.

The Meeting Holiday Spectacular
Dec. 20 & 21, 9:30 & 7 p.m.
