Subject: The Real Mother-in-Law           

Two Jewish men are on a train across Poland, each on his way to
meet a prospective bride on the other side of the country.
Halfway there, the first turns to the second and says, "Forget
about this whole marriage thing. I just don't like the idea."
So he gets off at the next stop and makes his way back home.
Meanwhile, the second man continues on and is met at the final
destination by the mothers of the two prospective brides.
When the mothers realize what has happened, they instantly begin to 
fight over whose daughter should wed this precious man. "He's mine!"  
cries one. "Not on your life," cries the other, "He will marry my
daughter!" After bickering for a while, the man and the two mothers
decide to go the local rabbi and ask him to resolve the situation.
In the grand tradition of the ancients, the rabbi replies, "Well,
there is only one solution to this problem. Cut the boy in half,
and you each take half home with you." At this, the first mother
looks shocked, while the second mother grins and cries emphatically,
"Yah! Cut him in half!!"  The rabbi points to the second mother and
says, "THAT is the real mother-in-law. Case closed."
