"I got this scar about four months ago, when my ex came over to my house. I thought it'd be funny, so I jumped on my pogo stick and went into the street. I hopped twice, and then kinda missed at an angle and the stick slipped out from under me. I scraped my knee pretty badly along the concrete; it actually took of two to three layers of skin. To top it off, my ex didn't come over - he just laughed at me!"
