Nicola Tesla was obsessed with doing things 3 times, 3 6 9 in the coin max, 3 minutes block time etc. Got to be him (or Mario Gomez).

Other than his death ray this is my favourite Tesla story

One version of the story has Tesla experimenting with a small version of his mechanical oscillator at his laboratory on 46 East Houston Street near the Manhattan neighborhood of SoHo. Tesla said the oscillator was around 7 inches (18 cm) long, and weighing one or two pounds; something "you could put in your overcoat pocket". At one point while experimenting with the oscillator, he alleged it generated a resonance in several buildings causing complaints to the police. As the speed grew he said that the machine oscillated at the resonance frequency of his own building and, belatedly realizing the danger, he was forced to use a sledge hammer to terminate the experiment, just as the police arrived.[5] Other versions have Tesla smashing the device before the police arrive and have multi-ton equipment in the basement moving around. Another version has Tesla clamping an oscillator to a building under construction and causing it to vibrate so violently the steelworkers working on it left the building in a panic
