Has an AFL game ever ended 61-40?
Exactly once. On August 2, 1902, Fitzroy beat Geelong 61-40, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 61-40 in league history.
That makes 61-40 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 62-40 has happened 1 times and 61-41 has happened never.
