God greets Mother Teresa at the Pearly Gates. "Art thou hungry, Mother Teresa?" asks God. "I could eat," Mother Teresa replies.
So God opens a can of tuna and reaches for a chunk of rye bread, and they share it. While eating this humble meal, Mother Teresa happens to look down into Hell and sees the inhabitants devouring huge steaks, lobsters, pheasants, pastries and fine wines! Curious, but deeply trusting, Mother Teresa remains quiet.
The next day God again invites Mother Teresa to join him for a meal. Again, it is tuna and rye bread. Again, looking down, Mother Teresa can see the denizens of Hell enjoying caviar, champagne, lamb, truffles and chocolates. Still Mother Teresa says nothing.
The following day, mealtime arrives and another can of tuna is opened! Mother Teresa cannot contain herself.
She says: "God, I am grateful to be in heaven with you as a reward for the pious and holy life I led. But here in Heaven all I get to eat is tuna and a piece of rye bread and in the Other Place they eat like emperors and kings! Forgive me, O God, but I just don't understand..."
God sighs. "Well, to be honest, Mother Teresa," God says, "....for just two people, does it pay to cook?"
