Fed up waiting, the Shamus approaches the Rabbi. "Rabbi, why are you waiting? Please start your speech".
The Rabbi points to his mouth and whispers to him "I left my false teeth at home".
The Shamus takes the Rabbi's keys and runs to the Rabbi's house, returning shortly with the false teeth.
The Rabbi starts speaking. He talks and talks. It is getting late, everyone wants him to finish. They want to go home, but the Rabbi keeps on talking.
The Shamus approaches the Rabbi and asked politely, "Rabbi, why do you talk so much..."?
The Rabbi answered: "You brought my wife's teeth".
