A man goes into a bar and drinks beer. After every glass of beer he pulls a picture out of his pocket and looks at it. After the 4th beer the waiter asks him why after every glass of beer he pulls the picture out and looks at it.
Then the man says: "It's a picture of my wife. When she looks good to me I'm going home."
That is an example of the "The Power of Beer" Be sure to click where it says "click here" (That's the neat part.)
