This is spooking me out. It's freaky. Happy Halloween.

What are you?

-Okay, it has a really long explanation,

which makes my costume, like, you know,

very characteristically weird and awkward,

because it's not like I'm a dead baseball player.

My girlfriend is a dead cheerleader.

She's, like, a fearleader.

And she was like, "You know, when people ask us

what we are, we should just be like,

"Well, we're socially irrelevant,

hetero-normative gender roles that are dead.

-Wow! Oh, my gosh. How 2019 of you.

-I know. It's embarrassing. -I'm so happy you dressed up.

Do you normally -- What is your go-to Halloween costume?

-I like to be a vampire. Yeah. -You can't.

-I know. -You can't.

-Well, I like people to talk about me.

You know what I mean?

-But you're in the "Twilight" movies.

You can't be the vampire.

-No, but it's more like "Lost Boys."

-Ooh! it is "Lost Boys." Ooh! I like that.

Do you go all out?

Do you decorate your house and everything?

-Yes. -You do?

-Yes. I do. Well, I have done, yeah.

-Yeah, I don't really go for it that much.

I don't really like to get scared or any of that stuff.

-Oh, really? -I'm not really into that.

No, no. -I don't get scared.

-You never get scared? -I don't get scared.

-Boo! -[ Laughs ]

You really don't.

You laughed at me.

-This one year, I went, like, so completely wild at my house

that my neighbors complained.

I had, like, a whole sort of, like, scene, murder scene,

with, like, a mattress that I did this to.

And then the parents came, and they were like,

"My kids are terrified, and this is inappropriate.

And it's too far."

And then I had other people coming up being like,

"Don't even listen to them."

Like, the cool-mom thing, and I was like, "Okay.

I'll get the body off the bed, but the bed stays."

-Oh, wow. -Yeah.

-You're a good neighbor.

Yeah, that's very nice, you don't creep them out too much.

-I don't want to make kids, like, cry and stuff.

-Of course not.

You're hosting "SNL" this weekend for the second time.

-Yeah, dude. -Are you psyched?

-I'm stoked.

-Is it fun? Is it fun up there?

-Yes. No, I feel less palpitation-y this time.

It's great. I feel amazing. Yeah, yeah.

-Yeah, 'cause you know most of the cast

from the last time you hosted, right?

-Mm-hmm. Yeah.

-That was a great show. I loved it.

There was a little, tiny hiccup

at the beginning after your monologue.

-I should just hiccup through my whole monologue this time.

Just be like... [ Hiccups ]

-That's pretty good, actually. I like that character.

But I don't know if you remember.

You cursed a little bit.

-Well, I'm getting reprimanded again now.

It's like, "I don't know if you remember, but..."

-Yeah. Unh-unh-unh. Get out a ruler.

-Yeah. -Yeah, what happened?

You just blank or you just...

-No, I was feeling really present

and in the moment, and so I didn't blank.

I actually was, like, really giving her.

And, yeah, it was like the one time

I stepped off the teleprompter, 'cause it's at the end,

and I go like, "Anyway, I am really excited."

Instead of "really," I said, not that.

-Yeah.

-And, yeah, it was -- I never, honestly --

I had, like, someone speak -- Numerous people come up to me

like four different times before the show,

because I had been, like, kind of stumbling through rehearsal,

'cause I was really self-conscious and embarrassed,

and I was like, "I can't do this until it's the moment

and, like, you know, it's game on."

And, so, I was like, "Yeah..." [ Mumbling ]

And a lot of that was cursing.

And then they were like, "You can't do that on the show.

You cannot do that on the show." And I did it on the show.

-After they told you, "Don't do it on the show," yeah.

-I was like, "Would I ever? What do you think I am?

I would never do that."

-Yeah, And then, right out of the gate, you did it.

-Yeah, yeah.

-But they loved you so much, they wanted you back,

'cause you were really good.

Aww! They love you, yeah. And Coldplay, which is awesome.

I heard their new record. It's fantastic.

-I just saw them rehearsing. It was really fun.

-They're amazing. We made Chris Martin --

-Chris Martin goes,

"Hey, Chris Martin from the band Coldplay."

-Yeah. -It was like, "Yeah."

-I kind of know who you are. Yeah, I know who you are.

Last time he was on the show, I made him do the worm.

I was like, "Do you break-dance?

Do you dance at all?"

He was like, "Well, I guess I could."

I go, "Could you do the worm?" And he's like, "Alright."

And he just did the worm all the way over to The Roots.

-That's full on. -That was pretty awesome, yeah.

-Do you dance? "Not really. Just kind of a little bit."

-I'm Chris Martin from Coldplay. Yeah.
