I found myself listening to The Postal Service for the first time in a while the other day. Specifically, "Nothing Better" in which we learn that he will "block the door / like a goalie tending the net in the third quarter / of a tie game rivalry." Are there any sports in which goalies tend nets and are divided into quarters? The imagine that comes to mind is hockey, but that's three periods. Alternatively soccer, but that's two halves. Water polo?
