Never
saw...but it is a funny story!
As a young teenager, I was awakened in the dead-of-night to hear the gate for the patio banging in the wind so I got up and walked (half asleep) downstairs to go shut the gate to keep it from making that racket. BUT...when I opened the sliding door, there was no wind and the gate was closed.
I was puzzled.
However, when I went back up the stairs I could still hear the banging noise, and deduced it was my folks' headboard.
