My aunt had a friend who lived on her own and was in her late middle age. She also lived at the end of a rather long driveway. One day she decided to take a shower, and didn't realise that she was out of clean towels until she had undressed and was looking for one to hang near the shower. She headed to the laundry room, and the doorbell rang. She wasn't expecting a letter or package. She had a sofa that faced a big picture window that was near the front door. She decided to drop down and hide behind the sofa. The guy kept ringing, so my aunt's friend decided to crawl back to the bathroom, throw on the clothes, and answer the door. In the meantime, the guy had gone around to the back of the house (in our area, it's not unusual for people to use the back door as the main door) and was standing at the back door, looking in the window just as she was passing the kitchen door, in the nude, on all fours, having just stepped on her tit with her knee.
Now this could be a total urban legend, but I know the woman, and it seems in character, and pretty hilarious.
