Have you ever seen the movie "The Wiz"? It starred Diana Ross, Michael Jackson and Nipsey Russell (among others).
Michael played the Scarecrow. He sang the Song of Thermodynamics. "You Can't Win, You Can't Break Even and You Can't Get Out of the Game."
Basically, that means you can't create more energy than you started with (win); your system is always inefficient (break even); there's nothing you can do about it (get out of the game).
