Mother Teresa died and went to heaven. God greeted her at the Pearly Gates.
"Are you hungry, Mother Teresa?" asked God.
"I could eat," she replied.
God opened a can of tuna, took a chunk of rye bread, and they shared the humble meal. While eating, Mother Teresa looked down into Hell and saw its inhabitants devouring steaks, lobsters, pheasants, pastries, and fine wines. Curious but trusting, she remained quiet.
The next day, God invited her to eat again. Once more, it was tuna and rye bread. Again, she saw the denizens of Hell enjoying caviar, champagne, lamb, truffles, and chocolates. Still, she said nothing.
On the third day, another can of tuna was opened. She could contain herself no longer. Meekly, she said, "God, I am grateful to be in heaven with You as a reward for my pious life. But here I eat only tuna and rye bread, while in the Other Place they feast like royalty! I don't understand."
God sighed. "Let's be honest," He said. "For just two people, does it pay to cook?"
