I wasn't thinking of counting the bee, wasp, and mosquito bites I've had 'til others counted them.

I was once kicked in the crotch by a milk cow such that I saw stars and wasn't sure I wasn't going to pass out.
Another encounter with a farm animal wasn't exactly an attack, but I remember it too well. I stepped into the barn just as a calf with diarrhea coughed; I was plastered from a few feet away, including a face full; it looked like butterscotch pudding, but you could tell the difference.

I was skinny dipping in a small lake when I felt something very startling; a small turtle (I think, never saw him) had nipped me..ah..on the "nose"; it left a bruise just like I had been pinched with a needle-nose plier. I've been half traumatized since, hoping it was a girl turtle...
