The first time I saw The Dark Knight Returns by Frank Miller on a bookshelf I passed it over because the first page was about a car race not Batman and I was immediately turned off. At the suggestion of a passerby I took a second look and realized it was about a retired Bruce Wayne forcing a car across a finish line, ignoring all the instruments and warning signals as the car bursts into flames that engulf the car (and seemingly the driver). I think about that scene a lot during the last rep of workouts.
