I was playing lawn darts when I was little. I ran over to pick up a dart and there was a bee in the grass by the dart and it stung my hand as I grabbed the dart.

My grandmother put baking soda on it. O_o;;

Edit: Oh yeah! One time during a soccer game I was running and a bee flew into my mouth as I shouted something. It stung me in the back of the throat. I stopped and was hacking until both the bee and the stinger flew out. It sucked.
