A man goes to see his 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, "Why do you think your wife is trying to poison you?" The man answers, repeating his suspicion: "I'm telling you, my wife is trying to poison me! What should I do??"
The Rabbi thinks for a minute, and then says--give me a week to get to the bottom of this, I'll call you back after I do. A week later, the Rabbi calls the man up and tells him: "well, I had a talk with your wife the other day. She was on the phone with me for 3 hours, non-stop... would you like my advice?"
The man says, "YES, PLEASE"... and the Rabbi answers, "take the poison."
