There are so many beloved Christmas movies. You’ve got your ‘40s classics like It’s a Wonderful Life and Miracle on 34th Street. Then there are several animated favorites from the ‘60s such as Rudolph the Red-Nosed Reindeer, A Charlie Brown Christmas, The Grinch Who Stole Christmas and Frosty the Snowman. The ‘80s and ‘90s brought hilarious picks like Scrooged, A Christmas Story and National Lampoon’s Christmas Vacation.

But the year 2003 was a particularly great one for modern classics, because it brought us two of the most endearing Christmas movies of the new millennium: Elf and Love Actually. (And Bad Santa, if that’s more your style.)

Believe it or not, Elf actually has its very own “holiday” today, in the form of Answer the Phone Like Buddy the Elf Day. Yes, this is a real thing, and yes, it’s today — December 18.

The point of this special day is simple: we’re supposed to pay homage to Will Ferrell’s lovable character by answering the phone like he does. Every. Single. Time. No matter who’s calling. It’s a great way to spread holiday cheer to unsuspecting callers (even telemarketers – ha!).

Here’s what you need to say:

“[Your name] the Elf. What’s your favorite color?”

Or you could also pretend you’re Buddy and use his exact line: “Buddy the Elf. What’s your favorite color?”

The thing I love about this holiday is that it’s based on such a quick, obscure line from the movie that you could easily miss. It’s uttered during a scene where Buddy is trying to wrestle the phone away from Walter (James Caan), his biological father, and he quickly gets cut off.

But I think the randomness of the line is exactly why people love it so much. There are a ton of great one-liners from Elf, but “Buddy the Elf. What’s your favorite color?” has sweaters, ringtones, memes, videos and more devoted to it. And, of course, today’s holiday.

So try to do it at least once. Perhaps you’ll want to watch Elf first for inspiration. Or really go all-in and don a green suit, yellow leggings and pointy hat for the occasion. (If you do this, PLEASE send us pics.)

Have fun!
