The man replied, "My wife is going to poison me."
The Rabbi, very surprised by this, asks, "How can that be?"
The man then pleads, "I'm telling you, I'm certain she's going to poison me. What should I do?"
The Rabbi then offers, "Tell you what. Let me talk to her, I'll see what I can find out and I'll let you know." A week later the Rabbi calls the man.
He says, "I spoke to your wife on the phone for three hours. You want my advice?"
The man said, "Yes" and the Rabbi replied, "Take the poison."
