"Australian football fan" joke

Australian Rules Football is, like the games of many countries, a game of spectator devotion. Kids are born as supporters of a team, and die that way. Especially Collingwood supporters.
For example: Friend of mine (yes, one of those sorts of jokes) went to the Grand Final one year. Couldn't find a seat. Went into the Collingwood stand, saw and old bloke sitting next to the empty seat. Went over to him.
"Excuse me, is this seat taken?"
"No, sit down mate"
"How come this seat was empty?"
"Oh I booked two seats, one for me and one for my wife"
"Is she ill or something?"
"No: actually she died last week"
"Oh sorry, I didn't mean to intrude on your grief"
"Its OK..."
"Why didn't you offer the seat to one of your workmates or family friends?"
"I would have done, but they're all at the funeral"
