"Honey," said the husband to his wife, "I invited a friend to come home for dinner tonight."
"But what are you crazy?" The house is a mess, I have not had time to go shopping, there is not a single cover and I do not feel at all in the mood to cook! "
"I know all that!"
"In that case, can you explain to me why you invited him to supper?"
"Because this poor guy is thinking about getting married."
