I have a couple.

I have three after the lipoma removals. I have one on the knee from when my brother hit me when we were sitting in a restaurant as there was a nail sticking out of the table. I also have this bump on my nose after a particularly nasty zit, but I guess you really have to know its there to see it.

Oh, and there's that scar from when I was a little kid. I think I fell asleep during some church ceremony and I have this horizontal scar on the bridge of my nose. It's really subtle though, so you have to know its there to notice.
