Has an AFL game ever ended 66-36?
Exactly once. On August 20, 1960, Carlton beat Geelong 66-36, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 66-36 in league history.
That makes 66-36 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 67-36 has happened 1 times and 66-37 has happened 2 times.
