Remember when Jaws the movie came out? The wife and I were in Woolworths (I think it was Enfield Town branch) when I saw they were selling toy rubber Jaws sharks, I grabbed one, looked around stuck it on the end of my nose shouting "ARRRRRRRRRRRRRRGHHHHHHHHHHHHHH GET IT OFF GET IT OFF." The wife nearly died of embarrassment when I was asked to leave. She never forgave me for that, she keeps on about it nearly 40 years later
Then on my honeymoon, we booked into our hotel on the Island of Jersey when someone asked, "Can I carry your bag upstairs sir?" I replied, "No let her walk like the rest of us." She keeps on about that one too.
