My son has a good one ...

Happily, I am scar-free - at least in the physical, visible sense, right? My son - my youngest of three kids - has a doozie on his forehead from one time when he took a digger running down our driveway, tripped, and went face first into the bricks lining the drive. He was super brave about it. And got it glued back together - instead of stitches.
