A man goes to see the Rabbi. 'Rabbi, something terrible is happening, and I have to talk to you about it.'
The Rabbi asks, 'What's wrong?'
The man replies, '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 to her; I'll see what I can find out, and I'll let you know.'
A week later the Rabbi calls the man and says, "I spoke to her on the phone for three hours. You want my advice?'
'Yes,' says the man, and the Rabbi replies, 'Take the poison!'
