I rolled a lawn mower over a nest of yellowjackets. It was just a hole in the ground so I didn't see it until the little monsters starting erupting up from under me. I got stung quite a bit, with a lot of them getting trapped under my shirt, in my hair and just buzzing everywhere. Now I tend to try getting someone else to do the lawnmowing. It's MANual labor, right? Let a MAN do it! (They don't scream as much as me and disturb the neighbors!)
