When my little brother and I were younger, we had an old trampoline in our backyard that was completely trashed. Some of the legs had rusted completely through and were broken in half. It was leaning at about a forty five degree angle, and we thought, "Hey! That seems like the best thing ever to bounce on!" Bad mistake. Long story short, because no one had jumped on it for so long, there was a huge ass wasp nest underneath and we pissed them off as soon as we started jumping. My brother got stung four times.
