Riding last summer I got a bee caught behind my glasses. Couldn't get them off because of helmet straps. Tried to stop as fast as I could, got off the seat and got my feet on the ground before bike stopped and panicked and hit the front brake too hard and had the back of the bike go over my head knocking me over the handlebars onto the ground. My thighs were black and blue for weeks. Didn't get stung though.
