Quote from : Back to the Future Part III Movie

Young Doc: [while exploring the cave that holds the DeLorean in it] This reminds me of the time I attempted to reach the center of the earth. I'd be reading my favorite author, Jules Verne. I spent weeks preparing that expedition, I didn't even get this far. Of course, I was only 12 at the time. You know, it was the writings of Jules Verne that had a profound effect on my life. It was when I was 11 that I first read 20,000 Leagues Under the Sea. It was then that I realized that I must devote my life to science.
