April Fools Day may have come and gone, but there are still plenty of pranks to be played.
Well, at least 10 (that we can show you right now).
The delightful instructional video above by Quirkology walks you through nearly a dozen ways to really get your friends on any day of the year.
All you need are some simple, household items like paper, water, ketchup (a practical joke staple) and, our favorite, this YouTube clip of a dog doing a backflip on a unicycle.
By the way, we wouldn't click that link until you've watched the video above. Share your favorite pranks in the comments!
