"Honey," said a husband to his wife: "I invited a friend home for supper."

"What? Are you crazy?" the wife exclaimed: "The house is a mess, I haven't been shopping, all the dishes are dirty, and I don't feel like cooking a fancy meal!"

"I know all that," the man replied.

"Then why did you invite a friend for supper?" she asked.

"Because the poor fool's thinking about getting married."
