Old Couple Trying to Have Children

70 year old couple wanted to have children, so they went to their doctor and told him that they wanted to have children. The doctor gave the couple a tiny specimen jar and told them to fill it up.
About a week later the couple went back to the doctor the man told the doctor, 'I tried with my right hand until it gave out, and I tried with my left hand until it gave out.'
And the woman said, 'I tried with both of my hands until they both gave out and we still couldn't get the lid off of that damm jar.'
