Note my previous fear of being bitten on the genitals!

This one time, at boy scout camp....
Yep, one kid got sent home due to such an unfortunate encounter with a black widow while in the latrine. The story goes that he came out screaming and that he told the first aid people "please don't amputate!"

Of course, I didn't see the event (the kid wasn't in my troop) and I expect the story was much embellished. In fact it might even be an urban legend (or rather rural legend). But I'm sure it must have happened to someone at some point.
