A wife has been married for seven years, has six kids and is tired of being pregnant. So she goes to talk to her priest. He tells her to buy a ten gallon bucket and stick her feet in it at night. She thanks him and goes off to do as he says. Six months later, the priest sees her and, sure enough, she is pregnant again. The priest asks her, "Didn't you follow my instructions?" She said, "Yes, but I could not find a ten gallon bucket, so I bought two five gallon buckets instead."
