Ask HN: Cool Things You've Done (Brag Thread)

I thought I'd start a "brag" thread. I know there are some really interesting and inspiring people here and I want to hear all the cool, unusual, unique things you have done.

Examples:

  * I've travelled to all 7 continents
  * I've won an olympic gold medal
  * I've built a start-up from scratch and sold to Google
  * I invented a consumer electronic device that has sold 10M units
  * I've produced a feature length motion picture [Insert Title]
  * I had this ... funny life experience
  * I went drinking with Vladimir Putin
