-Welcome back to "The Tonight Show."
We're about to play a game called "Box of Lies."
But I'm gonna need some help. She stars in "Stranger Things."
Season 4 premieres May 27th on Netflix.
Please welcome Millie Bobby Brown!
[ Cheers and applause ]
Come on, now. Come on!
Are you kidding me? Come on. It's so good to see you.
I miss you. -Good to see you, too!
-Millie, here's how it works.
We have nine mystery boxes containing objects
no one has ever seen before. Okay?
On your turn, you pick a box, take out the object,
and describe it to your opponent.
-Can I sit down? -Yes, please.
-Oh, my, I'm -- You're not even ready for this.
-No. Really? -No.
-You have to describe what's in the box, put it out there,
and then I and you decide if we're telling the truth.
I can't even look at you. Or if we're lying.
Okay? -Alright.
-Are you already playing right now?
I'm in your head right now.
-I don't even know if you know what I'm thinking right now.
-Yeah, I totally do. You have no clue.
Are you ready to go first?
-Oh, my God. -That's the way I talk.
That's the way I talk to you. -That was berating me.
-It was, right? All right, bud, you're up first.
You can pick the first box. -Alright.
-Which one? -Four!
-Four.
-He was so passionate about four.
-Yeah, he was very passionate about four.
-Alright. [ Audience shouting ]
-This could be a hint right here.
-Oh, my gosh! -Yeah.
It looked like it was a little light.
-No, I've just got huge guns.
[ Laughter ] Huge guns.
-Huge guns. Alright, bud. -Okay.
-Yep. [ Clears throat ]
-[ Chuckles ]
[ Laughter ]
-Okay. -Alright.
[ Dramatic music plays ]
-The music. Alright. Jimmy.
-Mm-hmm.
-Um, this almost looks like
a children's play set kind of.
You know? Something that a child would play with.
And it's the Demogorgon from the show,
a toy Demogorgon, painting E.T.
-A children's play set. -Yep.
Yep.
-What does that mean again? -I don't know.
It's up for interpretation.
-Children's play set.
-And It's painting E.T. with my eyeshadow palette
from Florence by Mills.
-Ah! Now, I know -- I love Florence.
-Yes. -I know your makeup line, yes.
-And, um, that's what he's doing.
With a makeup brush.
-E.T. Yep. Uh-huh.
E.T.. And you've seen the movie "E.T."
-Um, I don't know. Have I?
-You're very young.
-Am I?
[ Laughter ]
-No, I actually know how old you are.
Yes, you are young. But you've seen "E.T." before.
You loved it?
-Loved it. -Yeah.
What character did you love in "E.T."?
-E.T. himself. -Yeah, I know, but there's
other characters in there. How about the boy?
-I loved the boy. -Yeah. What was his name?
-Elliott. -Hmm.
You do know "E.T."
-Or do I?
Did I just read a synopsis before I came out here?
-So you have a child's play set, is what threw me.
That makes no sense to me, 'cause a child's play set --
-Well, do you have children, Jimmy?
-Yes. They don't have play sets.
-They don't have toys? -They don't have toys.
-They're not real. -Toys are banned from the house.
Toys are banned from the house. Only books.
A child play set to me seems like a swing set or something.
That's a play set.
-No. I mean like a toy almost.
You know, something that you go, "Oy, oy!"
You know?
-Yeah, a toy and a painting of a Demogorgon, E.T.
Too many details.
I'm going to say, Millie Bobby Brown, you lie!
-Owwww. -Oh, my gosh!
Are you kidding me?
[ Sad tuba plays ]
Come on. You're good. You know how to act.
Come on. What am I talking about?
Why mess with the best?
Why mess with the best? I'm sorry.
Of course you're going to be a good actor.
Which one, guys?
[ Audience shouting ]
-I'm going to put -- My "E.T." for later.
I'm going to put it this way.
-[ Grunts ] -I'm here with you.
-Okay. Alright. Here we go.
Phew.
Mm-hmm.

-Well, anyways. -But I knew four.
-It's my turn now. -Yes, it's your turn. Yes.

It woke me up. Okay, here we go.

And they're one of my favorites, actually.
I eat them on set quite -- -How do you see the bottom
if he's drowning in the -- -No, I see it.
I can see it from the top.
From the top angle, I see it's green.
-Okay.
-And also spaghetti is quite, you know, thin,
so I can see through the spaghetti.
-Oh, I know spaghetti, 'cause I was just lying about it.
-I know. I know. -Yeah.
So you're saying two spaghettis?
That's -- What are the odds of choosing two spaghettis?

I don't think it's this kind of hat.
You've accepted my suggestion far too quickly.
I don't believe that it's one of those beer hats.
