Bear attack.

When I was a teenager we used to hang out at a certain spot which was a clearing in the woods. We usually played kickball or stickball there. One day two old dudes walked across the field and we were yelling at them to get off the field. They just kept walking and some of my friends started swearing at them and calling them names (like old baldhead). Next thing you know a bear came out of the woods and attacked us. Killed the kids that were swearing.
