As a bonus, one episode remains firmly imprinted;
A bloke turned up at the television surgery with a problem with his arrse - piles, excessively sweaty ringpiece or some such complaint.
With no sense of irony the telly people give Dr Christian the gig.
"Just take off your trousers and pants and hop up on the bed face down" says he, that rare man who actually looks forward to going to work.
Bloke does what he is told and Dr Christian goes in for a Close Target Recce.
He suddenly recoils with a look of disgust on his face.
"When did you last have a bowel movement?" he enquires sternly.
"Er about five minutes ago" says the bloke tentatively.
"Well I strongly suggest you revisit your wiping technique" says the good Doctor.
Bloke didn't seem that phased.
I heard a similar tale (possibly one for the Urban Army Myths), about a Para who had to give a urine sample.
He duly picked up a sample jar and took it away for the sample the next day.
The sample was duly handed over to the Duty Medic, who took one look at it and stated -
"What's wrong with that, it's all cloudy"
"Oh right" said the Para " Well I did just have a w4nk"
