Wikipedia is an incredible resource, but every now and then it gives me pause. Consider the first two sentences about the seventh-inning stretch:
The seventh-inning stretch is a tradition in baseball that takes place between the halves of the seventh inning of any game. Fans generally stand up and stretch out their arms, legs, necks, backs, calves, fingers, elbows, and other muscles and sometimes walk around.
Is the whole list really necessary?
