It's unclear why it has become traditional for supporters to go to matches on the final day of the season wearing fancy dress costumes, but it certainly makes for a colourful sight.
A group of Rangers fans stole a march on supporters of other clubs by dressing up in superhero fancy dress for the game at Hibs on Sunday.
Photos in the Scottish Sun showed the lads dressed as Batman, Robin, Bananaman and the Thunderbirds. Perhaps they chose the costumes to reflect their team's heroics in winning the SPL title - although if that is the case, we aren't sure what the fan wearing only a pair of Superman briefs was thinking of!
Expect more superhero fancy dress this coming weekend when the Football League season reaches its conclusion.
There are bound to be Newcastle United fans in Spiderman costumes in honour of Argentina winger Jonas Gutierrez, who celebrates his rare goals by pulling on a Spiderman mask.
Don't be surprised if you also see a couple of Incredible Hulks in the stands, while there are some fellas who won't be able to resist the temptation to dress up as a woman for the day.
