- Hey guys, welcome to "Stir Crazy".

Our guest today stars in "Riverdale"

which is making a seven year time jump this season.

I've aged at least 20 years this past season,

so that sounds perfectly reasonable to me.

It's Madelaine Petsch.

Hey. - Hi Josh.

Did you write that down ahead of time?

That was really good.

(Josh laughs)

- That came right off the dome.

- That's incredible.

You were so good. (Josh laughs)

Somebody get this guy a raise, please.

- Yeah.

This is the best guest we've had yet.

Any big resolutions this year?

Are you doing dry January?

Any big life changes?

What's going on? - My whole life is dry.

(Madelaine laughs) So.

In the sense of alcohol,

I'm not really a huge fan. - Got it, got it.

- But my life is incredibly,

I was gonna say moist (Josh laughs)

but I think fun is a better word.

(Madelaine laughs)

- Took about 30 seconds

for you to say something inappropriate,

thanks, we did it. - You're welcome.

- The "Riverdale" cast

is like the most powerful social media force

I feel like on the planet.

All of you guys.

Well you guys have like six gazillion followers

combined. - You know what?

Have you heard of this new app called Tik Tok Josh?

- I have. - They are taking

over the world.

It is not us.

- Where do you stand on the KJ Apa

enthusiastic shirtless dancing on Tik Tok?

- I love KJ.

When he put it out I did text him and ask,

was that meant to be posted?

So you know it is what it is.

You know what though,

I have to say like I love Instagram stories too.

He does this really funny skit stuff,

it just comes right out of his head.

A lot of people think he's insane,

but honestly I think he's a genius.

- What about your buddy Vanessa's Twitter?

She's kind of like very positive, new age-y,

there's crystals, there's astrology.

- I love her so much.

(Josh laughs)

- You know I actually

don't have the Twitter app on my phone.

I haven't had it for like four years.

- Oh you're probably very healthy

and well-balanced unlike me. - Mentally,

I'm still mentally unstable.

(both laughing)

But it's a little bit better than it would be otherwise.

- I also admire Kamilla's Instagram

if for no other reason

that she at one point posted a bunch of penis latte art.

- She made one this morning.

- That's like just a thing she keeps doing.

- Yeah.

(both laughing)

- As a friend, is this a good thing?

Are you worried about her, do you support?

- She's an artist.

Why would I ever be worried?

I don't get it.

- So okay the big exciting news on "Riverdale" this year

is you guys are making the big time jump,

seven years into the future.

Are you relieved that you're going seven years ahead?

'Cause I assume you wouldn't wanna play Cheryl at 10.

- Yeah seven years behind I would've lost my job, for sure.

(both laughing)

- Although it would've been entertaining I think, yeah.

- Definitely.

- So "Riverdale" is known for taking some big swings,

safe to say, plot wise.

Like, the writers go for it.

- I don't know what you're talking about.

I'm not familiar with that.

- So I wanna pitch you a few ideas, for future

seasons of "Riverdale". - All right.

- You tell me if these past muster with you.

(upbeat music)

"Riverdale" the golden years.

So you know we've moved ahead seven years this year,

screw that we're going ahead 70 years.

You're in the retirement home,

the mystery is who brought the chlamydia in.

What do you think?

- You said it not me.

- Well?

That's a real

thing by the way. - Well then

I'm out of a job again.

I've heard about this and I find it fascinating.

But also, I'd still be out of a job at that point.

- Well you don't know. - Don't know

if I could really.

Are you saying I could play an octogenarian?

- I'm saying you are capable of anything

with modern technology,

mocap suits. - That's very sweet.

Thank you, okay.

- I turned it around.

Thank god. - I accept.

(both laughing)

- What about "Riverdale" fury road?

It's dystopian.

Would you shave your head to kinda go Furiosa style?

How do you think Cheryl would be

in a post apocalyptic landscape?

- You know what?

I have said and I will say it again,

that I would shave my head for the right role.

But I don't know if like season six of "Riverdale"

in the dystopian future is the right role for that.

Feel like I don't need to.

I feel like my hair's fine on my head.

- Okay, we know where you draw the line.

I thought you would be more adventuresome,

but cool, whatever.

- Okay.

Fine.

- "Riverdale" Tokyo drift.

This is kind of a fusion of the "Fast and Furios" franchise.

The truth is this is just Vin Diesel

playing all the roles in "Riverdale"

so you're out-- - Oh I'm down.

(Josh laughs)

I would watch that show.

I'd watch that show.

Vin Diesel playing Cheryl Blossom, 100 percent I'm in.

- Do you think he'd look good in the red wig?

- He doesn't need a wig, he's a bad bitch.

(both laughing)

He doesn't need any accoutrement.

- He's so strong he could probably like will the red hair

out of his bald head.

(Madelaine grunting)

- Just.

(both laughing)

- Exactly.

So you are in the bubble with your cast mates.

So I saw for instance, what last Halloween

I saw some of you and your buddies

posed as what like Power Puff girls, do I have that right?

- What do you mean, what?

Obviously.

Obviously we're Power Puff girls.

How dare you.

- What's the next group costume party?

Like have you already scouted out,

like planned out the next five Halloweens?

What's it gonna be?

- I don't know where I'm gonna be next Halloween

so I can't do that can I?

- Well but you can have costume aspirations, costume dreams.

- Costume dreams.

Oh wait I came up with the best one yesterday.

I'm gonna be Gollum, I just remembered.

(Josh laughs)

Sexy Gollum, I think it's like

the most iconic. - Sexy--

- No one take this idea.
