Not a very impressive list but:

• (2004) Big toe got stuck under the bathroom door. Half the nail broke off and was bruised black for 6 months.
• (2007) I fell on a wooden plank with a nail in it at school. I didn't break my leg though I couldn't walk for a week. There is still a slight dint from it on my right leg.
• (2008) Tied a normal scooter to a motor scooter with my friend Vanja. We rotated turns on each scooter, and when I was on the back one it flipped and I got dragged along. There was a huge gash on my leg that got infected.
• (2008) When Megan threw a ruler at my head in year 7.
• (2011) When I was ironing shirtless and I got my stomach with the iron. It left a small scar.
