hmm, once I was riding a bike, and hit an old ball, the kind they sell at supermarkets for little kids. The handle bars on the bike, had grips, but they'd been pushed up, so themetal came thru, and the handlebar twisted, so that, as I flew over the bike, the bar dragged along my stomach, good thing I'd been going fast, or else I might not have flow so well, and might be a few octave's higher.
