My favorite fact about Elon Musk, which I learned from a talk given by one of the Tesla founders:
Elon Musk was not there when they founded Tesla. He made an investment in Tesla later on, and one of the things he wanted in return for his investment was to get the title "Founder of Tesla". He literally bought the title.
