V3.0 managed to acquire the first injury of my family requiring medical treatment, splitting his head open jumping on the chairs in the kitchen. He didn't land square and actually popped the seat off (metal tube frames) and took a shot to the noggin. One stitch. If I'd been on hand, I'd probably have jsut closed it with a butterfly, but as I was 100 miles away, the missus took him to the local ER. They didn't even bother to shave the hair around it. He was more bummed out about not being able to swim for a week than about having a hole in his head.
