On my dad's side, we had a cousin named Chris. He was a very spoiled child as his room always had the best video games and other stuff. He also had his own go-kart in the backyard. I remember he had to crank it up like a lawn mower, but like many things with small engines it gets tougher with time. So one day he tries to pull the cord, and he was maybe too successful after a struggle. As the go-kart sped away without a driver. Luckily it stopped before any kind of accident, but it was funny seeing him run like crazy to get it back.
