The worst non-surgery scars I have are from getting hit my a car when I was 15. I, and my bike, tumbled over the hood of the car. The bike was pretty much totaled. I luckily was pretty much ok, I landed on my backpack with a new bag of Smartfood brand white cheddar cheese popcorn. There was popcorn everywhere. It was estimated that the corvette was going 55 in the 35 zone. Road rash scars can be persistent.

The worst cut scar I have is from falling off a sofa when I was 10. My parents had 're-upholstered' it with a staple gun. During my fall I caught one above my knee. The scar is about 5" long and 1/2" wide and still shows up with high contrast.

The worst self-inflicted cut I have was with a waki. When not paying attention, the Arctic white blade coating looks a lot like the cardstock sheath. I badly cut my little finger and slice two other fingers. I probably should have had stitches but did not want to pay for them or let The Wife know how badly I screwed up with my expensive new toy. Super glue works pretty well. It took a long time to heal but now only the little finger shows anything and it looks like a callous.
