A rather prim female MP was visiting a local hospital in her constituency.
During the tour she came across this gent in a ward who was masturbating, she turned to her guide and asked the reason for this quite unreasonable behaviour.
She was told that it was quite normal as the patient had to relieve the pressure to stop a build up of seminal fluid in the scrotum that could, and probably would, result in severe infection.
This accepted she continued her tour.
A short while later she came across a private room into which she entered and found a nurse giving the patient a blow job.
Well, this was just too much but she, nonetheless, asked the quetions.
She was told that this patient had the same problem as the one seen earlier.
"Why then" she asked "Is he having a blow job?"
Well, said the Matron . . . . . . . . . . . . . "He's in BUPA!"
