Flip side of the question: I don't want to see multiverse/alternate universe/alternate timelines. At best they cheapen the stakes, at worst they remove them entirely. Oh noes, Wolverine has died but no matter we have a gazillion spare Wolverines, we'll just use one of them. Oh noes, Earth #2471893 might be destroyed but no matter there's an infinite number of other Earths. Etc.
A colleague and I were sitting waiting for a shit-ton (UK Imperial, not metric) of files for the project we were working on to be copied to a backup folder when our (pretty computer-clueless) boss wandered up behind us and said (with no irony at all - he was called Wolfgang): "Playing a game on company time?"
But then we all also wrote scripts which printed meaningless computer gibberish to the screen so we could take a bit of time out and relax - and if he ever showed up we'd be allL "It's compiling" or "It's recalibrating the main drive" or "It's defragging the video ROM".
I thought we were on time travellers' café/diner. Everytime he kills JFK, hoping for a different historical outcome each time, he comes here afterwards for the breakfast special.
I’d stand on street corners telling everyone who passed by that one day people would be putting pineapple on pizzas.
