Dinner invitation

[Alsatian]

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

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

"I know all that."

"Then why did you invite a friend for supper?"

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