I randomly stumbled across this today.
Some time back I had a brief flash of an idea for a sci-fi story I’ll never write, partially because it seems entirely too derivative of “Sliders.” In short, some people are hopping either timelines or alternate realities, trying to find their way home. Finally they get home. They check the local history books, newspapers, CNN, internet… everything confirms they’ve made it back to the right timeline. Finally, after they’ve settled back in, one of them is at a comic book shop or a coffee shop or something and overhears some Trekkies discussing what their favorite episode is… and someone mentions the episode from season six when Captain Kirk and Lieutenant Rand finally get married. The character realizes that this is a different timeline, one where the original Star Trek series didn’t get cancelled at three seasons, but lasted at least twice as long. Character shrugs, goes back to drinking his coffee, surfs over to Amazon and buys the complete eleven-season Blu Ray set of Star Trek.
