I lean over to reach around the back of my chair, and I feel this extremely painful sharp stinging feeling in my leg. It felt like someone took a large sewing kneedle, and jabbed it into the side of my knee. So I get up and change chairs, and pull up my pants leg. While I'm looking at my knee, two red dots appear and start bleeding. By this time, the pain feels much greater. About 20 seconds later, it starts to welp. I take my pants off, flip them inside out, and low and behold, walking around the knee area is a wasp. The little bastage crawled up my pants leg and stung me twice in the knee cap. How ironic is that?
