Undescended Testicle I believe it's called. When your very young your testicles are pretty much inside you and they slowly come down. One came down and the other one didn't. So they moved it to the proper spot. Messed up things could happen like infertility and cancer if not treated. There's a tiny black spot on one of the jewels. It's a suture of some kind where they secured it down.
Lol it happened man it's one of my favorite childhood stories with my friends. We were throwing a frisbee after school and I just didn't see this kid chasing the frisbee. We hit really hard. His lip and nose were bloodied while I didn't look too bad except my eyes were stuck up in my head. If I tilted my head down I could see a small slit of vision. So we all walked up to the office but by the time I got their they just came down. I don't know if I had a muscle spasm or what it was. It was really weird though.
I also have seen a one in a million explosive diarrhea episode that was left in a bi-lo grocery store bathroom. Doctors haven't really explained that either, they just said people get really sick. sometimes. I'm still not sure if it was somehow a prank or something. The coverage was physically astounding.
Lol. Damn dude.
