Has an AFL game ever ended 67-42?
Exactly once. On August 31, 1929, St Kilda beat Footscray 67-42, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 67-42 in league history.
That makes 67-42 the 3884th most common final score out of 6,649 that have ever occurred in AFL. One point away, 68-42 has happened 3 times and 67-43 has happened 3 times.
