20 years. Do you believe that?

-I do. Yeah, you were --

-I lived it, yeah. Yeah, you were --

That was you. Well, this is you

and your brother, Dylan Sprouse,

on "The Tonight Show with Jay Leno."

[ Audience aw's ]

I can't even tell which one is me.

That's you.

-Yeah, yeah. -That's you right there, yeah.

-Uh-huh. -Look at this little guy.

What do you remember about that, anything?

-Uh -- nothing. -No, nothing?

[ Laughter ]

I remember my brother -- and you can see by --

by his posture, he was talking the whole time and I was

actually sitting the same way I am right now.

-You really are just sitting just like that.

-Now that I realize it. -That's how you sit, yeah.

Amazing. But you --

Look, Jay's holding a picture.

You drew a picture of Jay Leno. -Yes.

And gave it Jay.

Which I -- we had a zoom-in of that which is kind of --

Well, it's just interesting.

[ Laughter and applause ]

I mean, you were young. -I --

-You were young and --

-Well, in keeping with tradition,

I actually drew you one tonight, as well.

-You drew a picture of me? -I did.

I wanted to make sure that we -- we kept this in line and --

-Well, this is a tradition. -I mean, it's been

a little while so -- -Yeah, it's been almost

20 years later. I'd love to see it.

A little bit better. -Thank you, buddy.

[ Laughter ]

[ Cheers and applause ]

There it is, right there.

Fantastic. Wow.

[ Band plays ]

[ Cheers and applause ]

Not bad. I mean, you've gotten better.

I can definitely see the improvement.

It's just amazing. I love it.

-You don't like it? -I will cherish this.

Are you kidding me? I'm gonna hang this on my fridge.

-Do you like it? -I'm gonna hang it on my fridge!

[ Laughter ]

-Thanks.

-Uh -- I love that, pal. Thank you for doing that.

I also want to thank you... -It took a lot of work.

...for doing. I want to thank you for doing

this thing you're doing on Instagram.

Do you know what I'm talking about?

Camera duels?

Camera-underscore-duels. Now here's the idea of this,

and this is why I think it's very funny.

Now and then you go out and people recognize you,

and they try to sneak photos of you.

And they, like, put their phone up and they sneak,

and they act like you can't see what they're doing.

-Yeah. -You beat them to the punch.

You take a picture of them taking a picture of you.

-Yes. -And post that photo

on Instagram.

-And it's -- -It's a real process of shaming.

No, it's --I think it's just --

Here's one girl, she's like, "Well, I'm just not --

I'm like -- what am I doing?

[ Laughter ]

What am I doing? I'm not doing --"

-You were much kinder than me. You blurred out the face.

-Yeah, yeah, yeah, I did, yeah.

We had to blur out the face here.

-Right. But then, here's a girl

on the airplane, and you're just like, "Nah, what?

I'm just checking my e-mail on, like --"

That's pretty blatant right there.

-It blends in with her shirt, too.

-Oh, yeah, the phone itself is almost camouflaged.

And then here's a picture of this -- KJ Apa.

Is KJ napping? -No, that's just

his normal state of being.

[ Laughter ]

-You have to paint his eyes on during the show?

-Right. -I love that girl right there,

back there. But now --

So, camera duels --

If you want to see, they're very funny, but now it's kind of

backfired on you. -Well, yeah, I mean,

it starts as any other small art project through, like,

rage and annoyance and existential dread.

-Yeah. -And I -- I never --

I never imagined that when I started doing this

and started making it game it would, one,

be a small therapy for this situation that happens

all the time, but it would also inspire

everyone to start doing it.

Which is problematic. And when were in school

it was just a nightmare. So now people are trying

to fight to actually get on the Instagram which is completely --

-They actually want to be on camera duels?

-Completely backfired for me.

-So now they actually do --They're like, "Don't catch me.

Don't catch me." -Right.

They're like, "Can you see me?"

0"I can't believe you got me. I'm totally --"

-"Whoops." -"I just had a blowout,

I can't believe it. Oh!" -Right.

[ Laughter ]

-Can we talk about "Riverdale,"and maybe give us a spoiler

or something fun? You don't have to, but maybe

just sneak-in, and so we won't even get it now, but then...

-Right. -...when you come back months

from now -- -Yeah, I die.

[ Laughter ]

-Alright, alright, alright. That's a good hint, okay.

But -- [ Laughter ]

Season two happens, right?

And I'm all excited about season two.

And man, oh, man, it gets scary.

It's frightening. It frightens me.

[ Light laughter ]

Hard -- The first scene --

-Do you want me to comfort you? Is this is why you're --

-I just want you to feel my --what's going on

and analyze it and tell me what's up.

But you --The first season, i go,

"Oh, there's a murder. Some kids were killed,

and who shot these -- this boy?" -Who shot this boy?

[ Laughter ]

-You have a Southern --"Who shot this boy?"

-"Who shot this boy?" -And you can't --

and I've said this before, I think you have the best cast

on TV right now. -That's great.

-On "Riverdale," you guys are unbelievable.

Every single person on the show is fantastic.

And you work so well together. -Oh, yeah.

-And it's really, really fun. So then, season two happens.

-Season two, I'm riding a motorcycle

and wielding a switchblade,

which is something my little quivering Disney self

never thought would happen... [ Laughter ]

...if I'm being quite honest about it.

-This little guy has a switchblade and a motorcycle.

-A switchblade and a motorcycle.

-That is the greatest. -Right.

-No, you really are. I mean, you're --

You're in --You're in the gang now.

-I'm in the gang. -You're at a new high school.

-Uh-huh. -But now you have a --

It's the mid-season that premieres Wednesday night.

-Mm-hmm. -What can people expect,

or what should they do?Should they binge watch

what they haven't seen or get ready,

or can they just kick off? -Catch up.

The first half of the season has been us preparing for

this impending impossible riot.

And that --Much of Jughead's narrative

was him being positioned on either side of this

and trying to mediate this.

So the second half of the season is me in a leather jacket

with a comb on a motorcycle. -Yeah.

-One foot on either side of this impending war.

-Wow! That's what I'm talking about.
