Just in time for April Fool’s Day, we bring you the best You Tube has to offer where it comes to the funny, idiotic, ingenious, and just plain cruel. Whether you’re a practical joker or just enjoy watching others’ people fear, pain, and sick humor, the following pranks have one thing in common: They elicit the intended reaction. Laugh on, my friends, and let these videos be a lesson: Don’t be a sucker come April 1.

1. Scream Mask at Work

A clean take on a classic approach, with the best possible reaction.

2. Spoons

Okay, so maybe it’s staged…it’s still a pretty funny prank.

3. Ketchup-Filled Jelly Donuts

Mmmmm donuts. Or not.

4. Dan Cummins’s Scary Clown Suit

Imagine your friend’s surprise when he wakes up to a room filled filled with tiny clowns…

5. Japanese Mob Scene

This one gets technical points for being challenging to pull off, and for the of-the-moment flash-mob twist.

6. Fire Cracker Tied to a Friend

We don’t recommend doing this to anyone, ever. But the sadistic will get a laugh out of the video.
