Nikola Tesla once “shook the poop out” of a constipated Mark Twain with an experiment.
Most people don’t know that Tesla had a terrific sense of humor.
Twain was known for having digestive problems, so Tesla, who knew Twain through their gentlemen’s club, invited him over. He instructed Twain to stand on the platform while he flipped on the oscillator. After about 90 seconds, Twain jumped off the platform and ran for the facilities.
