Mine was walking down a spiral stairway in the Bayswater shopping centre. I see petite blonde woman with THE most fabulous backside standing on the stairs with her back to me. Came close to paying her a compliment on her amazing asset, but then noticed the camera crew down below pointing up at us. Turned out to be Annika Rice presenting live on national TV (she used to do some daytime TV show). That evening the mother in law called the missus and said she saw me on TV!
What are your near misses?
