Let me think, let me think . . . Oh, now it's coming to me. How about beer bong? The kids love it, especially those over active teenagers. Your wife will laugh and laugh while watching her kids stagger across the lawn. Nude nerf gun wars. Kinky, but then I shouldn't be surprised by your suggestion. Anyway, I'm in, but not if it involves mostly men or farm animals.
I had homemade lawn darts. My cousin, who was my age, at that time about 8, and I would take a ball point pen. We would remove the cartridge and replace it with some pins retrieved from grandma's sewing kit and scotch tape them into the tip. Then we would throw these things at trees, walls, whatever, including each other. Lots of fun. My aunt had a field day with a switch and our bare bottoms. But grandma reacted as though we could do no wrong. Love her memory dearly.
