A man goes to see the Doctor. 'Something terrible is happening and I have to talk to you about it.'
The Doctor asked, 'What's wrong?'
The man replied, 'My wife is poisoning me.'
The Doctor, 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 Doctor 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 Doctor 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 Doctor replied, 'Take the poison'
