Yeah, another idea stolen from SomethingAwful, but COME ON, it's fun to do!
You get the idea. Draw shit you regret doing when you were younger. Here's mine.
The story:
I don't really know what happened, I was only 3, but I think I got really, REALLY mad at my mom for some reason, and ran headfirst into a cabinet in our living room. I got stitches later at the hospital, and yes, I bought my Barney doll thing (hey, I was 3)
