you've seen your favorite stars

get completely transformed, and go totally undercover...

So good.

all to give kids and schools the surprise of a lifetime.

Smell like hot garbage to me.

Oh, my God.

Actor and singer Asher Angel

became a smarty pants substitute,

who knew everything...

Hello, students.

Except how to teach a class.

You want to see a folk dance?

- And his open-door policy was outrageous

in our hilarious number ten prank.

- Do you trust me? - Yes.

- An open-door policy, right? - Yes.

Open-door policy.

Oh, you rock.

You are really great.

Hey, hey, hey.

- Do you think-- - Mr. Chin.

- This is not good. Who knocked this down?

- Maybe I should go, you know? Thank you, guys.

You guys were wonderful students.

Hey, open-door policy.

Thank you. Well, have a wonderful meeting.

Wait.

Don't get it in my hair, okay?

It's just so annoying!

She's going to get fired.

- For our number nine prank, internet sensation

and breakthrough pop artist Jojo Siwa

convinced a class on a field trip

that she was an actual robot...

- I can't wait to show you guys this.

- What the heck? - Whoa.

- Despite some major malfunctions.

Sorry. It glitched.

What were we talking about?

I have a question.

- I don't think we want to find out.

Do you guys like to dance? - Yeah.

I like to robot dance.

Engage robot dance.

Robot dance not stopping.

System, stop.

System, stop.

Stop this arm. Somebody, please.

Thank you. Thank you.

Sorry, guys.

I might need control pad solution.

Oh, no, oh, no!

Help me get a paper towel!

Oh--I need them all!

I need them all. I need them all.

Help. This can't get wet. It can't get wet.

Can't be wet. I need more.

I need more, I need more, I need more, I need more,

I need more. System is wet.

System is wet.

Help! System, save to laptop.

System, save to laptop.

Okay, good.

- Uh-oh. - Why is that smoking?

Oh, my God.

- Not good. Malfunction! Malfunction!

Malfunction! Malfunction!

System malfunction.

Malfunction. Malfunction.

- Don't--don't touch it. Don't touch it.

Don't touch. This could be very dangerous.

That was strange. I'm a little glitchy today.

No, but why is it smoking?

- I mean, it's done smoking. I think we'll be fine.

Well, that's reassuring.

- I don't like staying at my friend's house.

Oh, no, no, no.

and I love the sun.

How my skin look? It look okay?

Ahh.

play tons of characters...

as a survival guide...

I think I'm prepared.

His unusual tips

became a complete disaster

in this savage number eight prank.

- Sometimes, you don't have order.

You have to use the rain storm brainstorm.

Sit down, 'cause this could get a little crazy.

But what's gonna happen?

Oh, yeah.

All right, so you put this on like this, so...

Can I get some volunteers?

- Me, me, me! - All right.

So water comes from the sky.

And who wants to shoot water at me?

Okay, so go in there.

Get the blasters.

Blasters. Okay, wait! Wait--oh!

Wait!

Wait a minute. Wait!

Wait.

PC! PC!

Yell out, "PC." kids: PC!

- PC! It's working.

Okay, I'm hydrated. I'm hydrated.

Oh, no. Wait, wait, wait,

what a minute, children. This is survival.

Hands up...
