My time traveling protégé, Diva, just informed me that today is the 55th anniversary of the day time travel was invented. How could I not know this?
Doc Brown: Here’s a red-letter date in the history of science, November 5, 1955. Yes, of course, November 5, 1955.
Marty McFly: What, I don’t get what happened.
Doc: That was the day I invented time travel. I remember it vividly. I was standi…ng on the edge of my toilet hanging a clock, the porces was wet, I slipped, hit my head on the edge of the sink. And when I came to I had a revelation, a picture, a picture in my head, a picture of this. This is what makes time travel possible. The flux capacitor.
Marty: The flux capacitor?
Doc: It’s taken me almost thirty years and my entire family fortune to realize the vision of that day, my god has it been that long.
