It’s April Fool’s Day, and you know what that means: for a solid 24 hours you are allowed, no required, to be a total jerk to everyone around you.

And while the day may be marked with your more tame tricks — the kitty litter in the office drawer, the bucket of confetti perched on an open door — there are some pranks that cross a line. These are pranks that deliberately hurt, terrify or inconvenience the other person for the sake of a cheap laugh.

Apparently that line doesn’t exist in other parts of the world, because their pranks are downright vicious. Enjoy!

Germany: Das Wasserpranken

We made that term up, but it describes this prank beautifully. And while maliciously dunking someone who is out for a stroll may be pretty cruel, this is actually one of the tamer pranks you’ll see today.

Skip the intro unless you speak German and hit the :14 mark where the fun starts.

To us, the strangest part is how everyone who gets dunked is sort of… OK with it? Like this sort of thing happens in Germany all the time.

Belgium: The Greatest Tour of Bruges Ever

This one comes to us from Belgium by way of England. Taken from the BBC series “Trigger Happy TV,” this showcases host Dom Joly at his finest. It’s a slow burn joke, but somewhere around the fifth lap around “The Big Square” which is decorated for “The Festival of Joy and Pleasure,” the brilliance of this gag reveals itself.

The fact that they don’t call him out on it until four minutes into the “tour” gets us every time.

Brazil: Mirror, mirror on the whaaat?

Such a simple setup, such a brilliant execution. Well done, Brazil. It’s a gag that’s been done since the silent film days, but turning it into a prank was a master stroke.

We almost feel bad for the cleaning lady who comes in at the 3:00 mark to clean the mirror.

Japan: Should have taken the stairs

And here we take a sharp turn from “lighthearted fun” into “deeply psychologically damaging.” The prank is essentially that the producers of the meanest show on television lure people into a fake elevator at which point they cut the lights, start piping in scary noises, then sneak in a guy dressed like a zombie samurai. Too far, Japan.

If you tried this exact same prank in the United States, you’d clog up the courts with mental distress lawsuits for years.
