Funny story, actually.
See, I had just come back from a camping trip with my school and I was waiting for a bus with two of my friends. Being the klutz that I am, I fell over because I was laughing so hard and had an overstuffed hiking bag on my back, so yeah

I fell backwards and hit my head on the edge of a square shaped metal pole. It didn't hurt except for the shock of the impact but as I stood up my friend told me I was bleeding... alot. My hair, neck and then my hands were covered in blood from the gash which was only like an inch wide but went all the way down to my skull (I found out with one of my fingers :O ). So I was on a bus for ten minutes, going home with a bloody gash in my head, which no one seemed to have noticed and then had to wait about 4 hours at a clinic before they got me sown up... It only took 3 stitches and a tetanus shot.
So yeah! Happy Birthday to me!
