So the lead programmer of 'Candy Crush' died and went to the underworld. Charon asks him "So what did you do in your life?"

"Well, I wrote this incredible game. You push a stone and then it crumbles. New stones fall from the top, so you can push those as well and so on."

Charon thinks for a moment. "But what happens when you've done them all?"

"Well that can't happen. You see, there are so many levels and they're designed to fail almost every time, so you can have endless fun."

Charon turns around. "Hey Sisyphus, you can go home. The new shift has arrived!"

Boom boom!
