A friend of mine was heavily pregnant with her first baby and she had to go to an ante natal appointment at St Mary's Hospital. Just before she was called in, she was given the obligatory jug and told to go and collect a sample of her pee. She did as asked but when she came to dry herself, she found that there was no toilet paper in her cubicle so she rummaged around in her handbag and found a tissue. Job done, she went in to see the doctor and had to get up on the bed and lie down ready for an internal examination. But as the doctor bent over her, both he and the nurse turned away in fits of giggles. It took them a while to stop laughing long enough to tell her that she's got green shield stamps stuck all over her nether end.
