Well it wasn't while I was brewing but its when I planted my hops on monday.. Was trying to push my empty wheelbarrow up some stairs in the backyard and thought I'd give it a little boost with my foot and my foot slipped and I slammed my shin into the little back support bar.. Dam little goose egg is not letting me forget about it.. it effin' hurts..lol that's probably the worst sofar because I don't count the steam burns that happen regularly
