45 - Back to the Future

Ben and Zane were enjoying the futuristic world of 2015, when suddenly they sensed a disturbance in the time stream. Their memories of the Back to the Future trilogy were fading from history, and soon they would disappear for good. They hopped into their time machine and headed for the past, but they had such a hard time concentrating on the problem that they ended up in all sorts of other timelines. They were too late (somehow), and one of their favorite trilogies turned into something far more generic. They would have worked harder to fix the problem, but they felt the whole endeavor was "too sad."
