"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 a fancy meal!"

“I know all that." Replied the nonchalant husband.

"Then why on Earth did you invite a friend for supper?" said the infuriated wife.

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