Armchair punters around Australia spent hours leading up to the AFL Grand Final bleating on about how he or she was going to get a payout of a lifetime through one of their "mysterious bets".

But one Sportsbet punter upstaged part-time gamblers everywhere after two of his $10 multi-bets saw him pocket a whopping $50,000.

One Facebook-user suggested the punter now had enough money to fix his phone.

The footy-keen punter's first bet was for Luke Parker to be the first goal scorer, Tom Boyd to bag 3 or more majors and the Bulldogs to win by 1-39 - delivering him a $25,010 payout.

His first bet almost seems easy, once you analyse his second wager, which reads like E=mc2.
