Divide and Conquer

A Jewish town had a shortage of men of marriageable age, so they had to import men from other towns. One day a groom-to-be arrived on a train, and two mothers-in-law-to-be were waiting for him, each claiming ownership of him.

A rabbi was called in to solve the problem. After a few minutes of thought, he said, "If you both want the groom, we'll cut him in half and give each one of you half of him."

To this, the first woman replied, "If that's the only solution, Rabbi, then do what you have to do."

The rabbi responded. "Ah...this is the real mother-in-law!"
