Ahh April Fools’ Day. In Korea, it’s called Man Woo Jeol (만우절 –萬愚節), which translates to “very foolish holiday.” A day when everything from tiny lies to faked deaths is, in the end, forgivable. Within reason.

Specifically in schools in Korea, it’s a time of teamwork and solidarity. One does not simply prank without the help and cooperation of every single schoolmate. Because that’s how you show everyone up, have fun, make lives difficult, and keep your teachers on their toes.

Here’s the best of the foolery Korean students engage in on April 1 every year:

A fundamental April Fools’ Day prank in Korea.. the class move.. to the soccer field.

But the show must go on.. sorry kids. Teacher found ya. And he brought his podium. (Students: 0; Teacher: 1).

If the soccer field is unavailable, then the roof it is. A collaborative effort between classes. That’s dedication. Yay teachers for playing along.

They call it the zero gravity class. I call it the lazy class. Look at your fellows out in the field! On the roof!

Where’s class 1-1…? Oh, there it is.

Creepy… but way to go getting everyone to wear their clothes backwards.

Invisible students? Psh. The REAL prank is 50 naked students running around somewhere. (Students: 1; School + innocent bystanders: 0).

I think she’s stuck. Immediate regret, is what this one’s called. (Student: 0)

“Teacher… It’s been… too hard… we’re sorry…” Morbid.

Nap time?

Either.. this guy fell asleep lying in wait. Or… nobody wanted to prank with him.
