Let's say you find yourself in the airport in Kuala Lumpur. A stranger approaches with a spray bottle and a fistful of money and points to a man who looks more than a bit like the half-brother of North Korean dictator Kim Jong-Un. Must be a coincidence, you think. The stranger explains that she'd like you to star in a hilarious prank TV show that asks ordinary citizens to spray random people with water for the lulz. What's the risk, right? Right? Wrong. Congratulations.
