Has an AFL game ever ended 136-37?
Exactly once. On May 20, 1978, Sydney beat St Kilda 136-37, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 136-37 in league history.
That makes 136-37 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 137-37 has happened never and 136-38 has happened never.
