If you played sports as a kid and scored a goal simply by standing in the right place at the right time for gravity to work its magic, you know what it's like to be a ninja for a day in the eyes of your peers. Catching things midair while a little tipsy, perfectly avoiding a fall, nailing the "throw it in the trash, walk away and know it landed perfectly in the trash" move at school, or getting to be a hero because you were luckily there for someone without meaning to are ninja moves. It's amazing when you get to do something expertly cool because you wanted to, but being unintentionally bad*ss is definitely a welcomed fluke.
One time, I was playing Badminton at a family picnic, and I hit the shuttle a bit to hard, and it flew over to the picnic tables; and landed perfectly in a plastic cup of water. Everyone saw it too. It was kind of awesome. - paradox1123
