|After a couple of years a couple wanted to have children, but nothing worked.So they went to a doctor, and got checked over.The doctor took time to reassure them. "Don't worry," he said, "Just takethis sample bottle home and do the necessary, and bring it back tomorrow."So he went home feeling better, and went back the next day with his littlebottle. It was empty. The doctor looked at the bottle carefully, " Problems?" he said. "Have I ever had problems, doc.!" the man replied. " I went home andstraight upstairs, and worked at it for over half an hour. Both hands. Itell you doc, my hands got too sore to hold it! I had to get the wifeupstairs and she had a go. But even she, with all her experience, couldn'tdo it. " "So what did you do?" said the doctor. " We had a discussion, and got the mother-in-law involved. I was sureshe'd manage it, but it was no go, even when she used her mouth. And doc,she tried with her teeth in, and her teeth out!!" "But nothing we tried would get the top off that bloody bottle!!!!!"
