I went outside to grab more wood. It was a little past midnight and so dark I couldn't see at all without my phone's flashlight. The third one from the pile buzzed very loudly in my hand. After the split second it took for me to realize I'm waving half a wasp nest on a stick while naked, I dropped everything and ran. I later investigated the other half of the hive still stuck on the wall; it was about 15 cm in diameter.
Second worst??? Wht on earth was the worst? An angry bear wrapped in poison ivy?
Stinging Nettles maybe, or whatever that mangrove tree that basically makes pepper spray when you burn it.
