Just when you thought you didn't have to be wary of our voice-activated future, Norwegian pranksters fool unsuspecting elevator riders with their improvised music and smart aleck-y prompts.

TO START, SAY "YES"

You know how it's scientifically proven that when we see someone yawn, we're biologically wired to do the same? Roman Atwood proves it in this prank video.

The World's Most Contagious Prank

Rémi Gaillard has been pulling elevator pranks for a while, but this one – featuring your favorite videogame characters – might have crossed the line.

NO, NOT PEACH. NO

SimplePickup and PrankvsPrank relay lines to tell girls through an earpiece, while still trying to get a phone number at the end.

DIFFICULTY LEVEL: HARD

For every good room listing found on Craigslist you'll have to waddle through twenty sh*t ones. Now add this morbid prank to the pile. Maybe a realtor isn't such a bad idea.

..AND THIS IS THE LIVING ROOM..

Nikki (of the prank couple Niiki & John) is getting revenge over a laxative prank that occurred one year ago. Bigger question: who plays videogames on the toilet?

UNCONTROLLABLE diarrhea

If a stranger tells you it's his birthday, even while you're talking on the phone, you'll pause to say "happy birthday." If he asks anything else, no way buddy.

WOULD YOU LIKE TO COME TO MY PARTY

RossCreations is forcing everyone to step their prank game up with this series of baseball-themed pranks, featuring not only impressive coordination but a clever imagination as well. Bravo.

LITERALLY STEALING SECOND

Is this even a prank? What if she outran the dude. The video is 20 seconds prank 90 seconds trying to calm the guy down.

UH, I'M NEW IN TOWN AND- CYA

Hello! I'll be your guide today. Here are some facts I just made up. Worms are dinosaurs with their limbs cut off.

IT'S TRUE

Yo girl, your butt is hanging out. And it's all plasticky and stuff oh it's a plastic butt.

DAT ASS

Maybe SEFD just wants to get killed. Try doing this in a different country — Italy… Vietnam.. and being arrested will be the least of your worries.

RIGHT OF WAY

Not really. Greg Benson has filled these jars with pudding beforehand, bringing them into the store himself. Just making me think of eating straight mayo is disgusting though.

YUUUUCK

Tom Mabe and Roman Atwood challenge people to a fight over the phone, telling them to "meet me here." Then they ditch the scene and let strangers take the heat, for a second at least.

I'M WEARING, UH, A WHITE T-SHIRT & BLACK JEANS

Vitaly offers Bang (the drink) to strangers. Ever heard of Bang, the drink? Me neither.

WANT TO BANG?

Garrett Garcia of Overboardhumor has seen enough videos of guys picking up girls. Truly, the hardest thing to do is to break up with someone. Bring in the expert.

IT'S NOT WORKING OUT

Ross of RossCreations throws down boxing gloves at a stranger's feet. He's got gloves on himself, and is ready for a fight. Halfway through, someone takes him up on the challenge.

COME AT ME BRO

NosTeraFu is wearing a Joker costume (because why not) quoting lines from 2008's The Dark Knight and annoying people in a way that's only vaguely connected to the movie character.

THIS CITY NEEDS A HERO

Using THE FORCE for real! Just have your friend hit the Open Door button from out of view, and fellow elevator passengers will stand back amazed. Annoyed as well.

JEDI KNIGHTS CAN BE DICKS

It's like Girls Gone Wild, but for measuring butts.

I NEED TO SEE IF YOU QUALIFY FOR MY PARTY TONIGHT
