Poison

A man goes to see the Rabbi. 'Rabbi, something terrible is happening and I have to talk to you about it.' The Rabbi asked, 'What's wrong?' The man replied, 'My wife is poisoning 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 poisoning me, what should I do?' The Rabbi then offers, 'Tell you what. Let me talk toher, I'll see what I can find out and I'll let you know.' A week later the Rabbi calls the man and says, 'Well, I spoke to your wife. I spoke to her on the phone for three hours.You want my advice?' The man said yes and the Rabbi replied,'Take the poison..'
