The 18th century was a time of rapid innovation; in the space of a single year, the two-storey building, the stage play, America, and the rocket launcher were all invented by the same man: Shakespearicles, the strongest writer who ever lived. Despite his powerful grasp of language and the ability to bench press 700 British pounds, several inventions eluded his iron grip - most tragically among them, stairs. For the next three hundred years, people who needed to get to the second floor used the only method available to them: shooting a rocket launcher at their feet. Yes, it was ridiculous, crippling, and awful, but what are you going to do? Not go to the second floor? That's where your bed is.
Rocket jump? That sounds dangerous.
