A drunk walked into a bar crying. One of the other men in the bar asked him what happened.

"I did a terrible thing," sniffed the drunk, "Just a few hours ago I sold my wife to someone for a bottle of Champagne."

"That is awful," said the other guy, "And now that she is gone you want her back right?"

"Right!" said the drunk, still crying.

"You're sorry you sold her because you realised, too late, that you still loved her, right?"

"Oh, No," said the drunk. I want her back because I'm thirsty again!"
