One day, this guy walks into a bar and asks the bartender for a drink. Then he asks for another. After a couple more drinks, the bartender gets worried.

"What's the matter?" the bartender asks.

"My wife and I got into a fight," explained the guy "and now she isn't talking to me for a whole 31 days."

The bartender thought about this for a while. "But, isn't it a good thing that she isn't talking to you?" asked the bartender.

"Yeah, except today is the last night."
