A husband and his wife advertised for a live-in maid to cook and do the housework. They hired a most comely young woman for the job. She worked out fine, was a good cook, was polite, and kept the house neat. She was perfect!
One day, after about six months, she came in and told the couple that she would have to quit.
"But why?" asked the disappointed wife.
She hemmed and hawed and said she didn’t want to say, but the wife was persistent, so finally she said, "Well, I’m pregnant."
The wife said, "Look, we don’t want to lose you. I am not able to have children and my husband and I would dearly love children. We’ll adopt your baby if you will stay."
She talked to her husband and of course he readily agreed, and the maid said she would stay. The baby came, they adopted it, and all went well.
After several months though, the maid came in again and said that she would have to quit. The wife questioned her, found out that she was pregnant again. She talked to her husband, and again offered to adopt the baby if she would stay. She agreed, had the baby, they adopted it, and life went on as usual.
In a few months, however, she again said she would have to leave. Same thing. She was pregnant. They made the same offer, she agreed, and they adopted the third baby. She worked for another two months, but then said, "I am definitely leaving this time."
"Don’t tell me you’re pregnant again?" asked the lady of the house.
"No.â€
 she said, "There are just too many bloody kids here to pick up after!"
