I was goofing around at the park as a kid, and climbed up to the top of a pavilion. I went to get down by grabbing the ledge under the roof and kinda flipping off the edge, but stuck my hand next to a wasp nest without noticing. I got about halfway through my flip and they stung the crap out of my hand, causing me to let go and fall flat on my back onto the concrete below. Screw wasps; Bees are cool though.
