You know you're in hell when you have to solve a puzzle to make anything freaking work. No wonder the devil's so cranky. He has to solve a sliding block puzzle every time he wants to open his bathroom door, complete a spot the difference to open the hidden door leading to his toilet paper, and rotate pipe segments to flush. He's supposed to remember an obscure passcode with individual characters etched into various rocks around his house so he can turn the sink on to wash his hands, but, well...now you know something new about Satan. Don't share complementary peanuts at bars with him, dude. Gross.
