I remember in '02 going to the arcade in the 2nd quarter cuz the Cs were getting whomped, and me and my buddy decided to make more productive use of our time.
We got back at the end of the 4th, and as the TV was warming up/turning on, I remember hearing "and with that free throw, the Celtics take their first lead of the game!" and we just looked at each other like "wow, what did we just miss here?"
