and I wanted to challenge you to something fun.

We all want to get in the holiday spirit,

so here's what we're gonna do.

I'd love you to start reading the classic poem

"'Twas the Night Before Christmas," okay?

And as you're reading, there will be names of celebrities

that pop up onscreen, okay?

So you'll keep reading but in the voice of whoever comes up next.

And you could wear that scarf if you'd like to.

You don't have to. -Ooh! Well, it does match my outfit.

-It actually really does. -Yeah. Holiday vibes!

-Okay, here we go. Ready?

Whenever you're ready, you can start

with the first impression that appears on the screen

right over there.

Ruth, can we get some sleigh bells?

[ Sleigh bells jingling ]

All right, here we go. -[ As Reese Witherspoon ] Okay.

Ahem. Okay, 'twas the night before Christmas,

when all through the house, not a creature was stirring,

not even a fierce little mouse, y'all!

-[ Laughing ] Okay. [ Bell dings ]

-[ Normal voice ] Okay.

[ As Drew Barrymore ] The children were nestled

all snug in their amazing beds,

while visions of the most gorgeous sugarplums

danced in their head.

[ Bell dings ] -[ Laughing ]

-[ Normal voice ] Oh! Okay, this one.

-Margaret Thatcher. -You got the teeth -- the teeth.

[ As Margaret Thatcher ] When out on the lawn,

there arose an unfavorable clatter,

I sprang from my bedchambers to see what was the matter.

-[ Laughing ] Oh, my God! [ Bell dings ]

-[ Normal voice ] Oh, good.

I have to pretend this is a shawl for Nicole Kidman.

-All right. -Okay.

[ Breathes deeply ]

[ As Nicole Kidman ] Away to the window I jumped like a 'roo,

tore open the shutters, and [laughs]

oh, my God what a view.

-Oh, my God. [ Bell dings ]

-[ Normal voice ] Oh. All right, here we go.

[ As Phoebe Waller-Bridge ] 'Twas a little old chap

so cheeky and quick,

I knew in a moment he must be St. Nick.

-[ Laughing ] [ Bell dings ]

-[ As Timothée Chalamet ] Uh, he -- he had a broad face

and a, uh, little round belly

that shook when he laughed like a bowl of jelly.

[ Laughs ] Nah, nah, nah.

I'm sorry, Nick. Nah, nah, nah.

[ Bell dings ]

-[ Normal voice ] Ah, okay. This one's fun.

Ah, well, you know, to get into Meryl Streep,

I kind of have to adjust my hair a little bit.

[ As Meryl Streep ] Ah, well, you know...

But I heard him exclaim, as he drove out of sight,

Meryl Christmas to all and to all a good night!

-Chloe Fineman, everybody!

That is how you do it right there!
