Playing the blame game
Accept the blame, even when it's not your fault. There are times when you've got to take the heat even though you're not in error. Sometimes that's just the way it is especially when your boss has backed himself into a corner. When the boss points the finger at you to cover up for his mistake, you've got to grin and bear it. Of course, you could go at head-to-head, and you might even prove your point. But you could also end up winning the battle and losing the war. When you do take the blame, do it quietly. This is not the time to act like a hero. In time, your boss will learn the real truth, and when that day comes, you'll score big-time points with him.
