June 24, 1374: Citizens in the streets of Germany start dancing uncontrollably, hallucinating, twitching, and jumping about like wild savages until finally collapsing from exhaustion. Dancing Mania has struck again! Science has no clue as to why this is happening. Some modern theorists say a basic form of LSD was responsible, but modern anti-theorists say "no way, Jose, LSD doesn't cause uncontrollable dancing". My theory is that Bill and Ted stopped by during one of their time travel adventures and rocked the town so hard that they couldn't stop dancing until their faces were pressed against cold gravel, their bodies too exhausted to even pee their own pants. What do you think happened?
