This wife has been married for seven years and has six kids
and is tired of being pregnant. So, she goes to talk to her
priest, the priest tells her to go and by a ten gallon bucket
and stick her feet in it of a night, she thanks him and goes
off to do as he says.

Well six months later the priest sees her and sure enough she
is pregnant again. The priest asks her if she followed his
instructions, she said yes but that she could not find a ten
gallon bucket so she bought two five gallon buckets.
