It's behind you........ Mk 2

With reference to my Blip of yesterday, well it will soon be Pantomime time.
I think back to an amusing incident in a waiting room in one of Liverpool's hospitals. 
A nurse had been out a couple of times calling for a patient, lets name him Mr Jones. She was told on the second occasion that Mr Jones had gone to the toilet, he appeared soon after she had returned to another room. Mr Jones god bless him, was a little confused and wandered about for quite a few seconds.  The nurse returned and called his name again.
The whole waiting room in unison shouted       "He's Behind You!" 
Scouse humour at it's very best.
