whats the most strangest thing you have seen in public

30 or so years ago, a friend and I were doing some roof work on a customer's big 2 story house. No one was supposed to be home. Lo and behold-we heard a girl's voice down in the yard on the backside of the house. We looked over the peak and the young teenage girl was laying on her back with her legs spread pulling her fairly large male dog on top of her. Saving face, she still had her pants on. That girl must have had some wild fantasies. We mad some noise without her seeing us and she got up. We both wondered how long this would have lasted had she not had her pants on.
