Back in the day before face shields I caught one of those little suckers inside my helmet while I was riding on a freeway. The impact didn't kill him, just pi--sed him off, so he started stinging!
It is amazing how fast a person can whoa down a motorcycle, put it on its stand, pull off gloves, undo helmet and stomp a wasp to death! The problem was that the half dozen or so stings on my head hurt like heck, caused my eyes to swell partly closed and start to tear up. It made the couple of hundred miles home a really unpleasant ride, and it started hailing too.
