A man walks into a bar and asks for a beer. After drinking it, he looks in his shirt pocket and then proceeds to ask for another beer.

After drinking the next one, he again looks in his shirt pocket and again asks for another beer.

This happens about another seven times before the curious bartender finally asks him, “Say, every time you order a beer, you look in your shirt pocket. Why is that?”

The man replies, “I have a picture of my wife in there. When she starts to look good, I’ll go home.”
