Should I lie?

Mr. Smith asked his wife for advice about his upcoming court case in which he could possibly win $50,000 from the insurance company. "Honey, if I lie I'll win the case. But then I would have broken an oath sworn on the Holy Bible."
His wife says, "I don't want to advise you to do the wrong thing, but..."
"But, what?"
"Let me put it this way," his wife explained. "Treat the prosecuting attorney like I treat you in bed."
Puzzled, Mr. Smith asks, "How so?"
Mrs. Smith replies, "Just lie there 'til he goes away."
