Bees

"In one horrific case in southern Africa, a man was attacked so relentlessly by honeybees that he had to jump into a river and hide beneath the surface. The bees continued to sting him every time he came up to breathe. The swarm was so dense he had to suck bees into his mouth and chew them to get any air. The attack went on for four hours, producing diarrhea, among other systemic effects, so that he was passing bees out one end while still ingesting them at the other. Finally, nightfall drew the bees back to their hive, and the victim dragged himself ashore. His face was literally black with embedded stings, and his hair was matted with dead bees. The doctors who treated him over the next few days counted 2,243 stings."

...and people wonder why I'm afraid of bees.
