Pranks can be fun, but some folks assume that the sole criterion of a prank is that it comes at the expense of others. And in those cases, "friends playing a practical joke" quickly devolves into "unrepentant sociopaths entertaining themselves." Here are some recent examples of that second thing.
4 A Cop Leads His Co-workers on a High-Speed Chase
Michael Milo Arbulic decided to prank his fellow officers of the North Vancouver Police Department by blazing through a speed trap at more than 37 miles per hour over the posted speed limit at 1 o'clock in the morning, because Arbulic was one of those kids we knew growing up whose idea of an April Fools' Day joke was to punch people in the chest and say "April Fools!"
"April Fools -- you're adopted."
He led patrol cars on a high-speed chase for over 3 miles before finally pulling over and identifying himself, although we assume he had to shout in order to be heard over his pursuing co-workers' urgent commands to put his hands in the air lest he be filled with more bullets than beads in a rainstick.
