Tired of Being Pregnant

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 and the priest tells her to go 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 that I could not find a ten gallon bucket, so I bought two five gallon buckets."
