Just came home from work and thought of some more.
When i was just 15 yo one of my first doors was a 30 something woman who opened the door topless.
Another time, my wife's skirt fell off while we were talking to some guy at the door... it was one of those Ricky Ricardo moments...ha!
Then there was the time my 5 yo son disappeared while I was talking at the door. I ran around the corner of the house and he was peeing on her rhododendron.
