Two can play at that game! We had a Plotter who was being as blunt as a very blunt thing and was behind the drag curve somewhat as we left Wildenrath. Late sorting out his mess bill, late for transport, late checking the NOTAMs.... So by the time we reached TOC he wanted to use the pee tube. I waited until he was at the point of no return, then pushed gently and he plus pee tube and contents floated gently upwards on the lower deck. Then pulled slightly and he ended up as a soggy heap on the crew entrance door!
Simple fun, happier times!
Unusually for the V-farce, our Plotter was as thin as a rake. He used to take a tatty blue striped dressing gown with him on night stops - when he came out of his room wearing it at Wildenrath I told him he'd better not let the locals see him in case they thought he'd been left behind when Auschwitz had been liberated.....
But he did have a nav's watch with all the extra dials which confused pilots!
