Everyone loves pulling off a good prank...especially when it's executed perfectly.
Maybe you swapped your roommate's hand sanitizer for lube.

Perhaps you did something like put Cocoa Krispies on meatloaf for a lil' surprise.

Or you could have pulled off something so elaborate that even you can't believe you did it. (Like when DJ, Kimmy, and Jesse manage to put a car on the roof in Full House.)
