How to ask for a raise

How does one ask for a raise? What? You saw the title and thought that this would be a "How to"? Not so much. I know I'm worth more than what I'm currently being paid and it's never more evident than when I'm out of the office for a day and there's a communication/understanding/productivity/overall office breakdown.

I feel I should immediately walk in tomorrow, stop in front of my boss's desk and say, "Show me the money because (as you saw yesterday), I'm more than worth it."

Oh if I only I had the balls! Which is another thing. If I had balls,there's no doubt about it that I would be paid more. It seems I get fu%$ked coming and going.
