Witnessing a goalkeeper score even once in a game is enough of a rarity, but a hat-trick from a keeper is usually the stuff of legend.
There are a few exceptions to the golden rule that keepers aren't goalscorers - Jimmy Glass and Peter Schmeichel, to name but two - while Oscarine Masuluke of Baroka even earned a Puskas Award nomination despite wearing goalie gloves when he scored a bicycle kick in South Africa.
Grigoris Athanassiou is the latest name to add to the list, though, and his treble in the Greek fourth tier is unlikely to be matched any time soon.
Athanassiou's goals might not have come at the highest level, but that is unlikely to matter too much after the veteran's remarkable feat.

37-year-old Athanassiou has some top-flight experience to his name, from stints in Greece and Cyprus, but has since dropped down the pyramid.
He took to the field for Pavlos Melas AO for their game against Aetos Vassilikon, and scored all three of the visitors' goals in a 3-0 victory.
The most surprising part? According to the keeper's Transfermarkt profile, he never scored a goal of any kind during his top-level career.
Not that you could tell, of course.
Athanassiou steps up like a seasoned pro for each of his spot kicks, even taking a leaf out of the book of Chelsea and Italy midfielder Jorginho with a hop, step and jump approach which gave his opposite number no chance.
While he might not have been a regular from the spot during his career at the highest level, one imagines he has shown his quality in training in order to have been trusted on the pitch.
Athanassiou is in good company when it comes to penalty-taking keepers.
Former Bayern Munich man Hans-Jorg Butt famously beat Juventus ' Gianluigi Buffon from the spot in a Champions League not once but twice - one for Bayern and one for Bayer Leverkusen - while also netting for Hamburg against Juve when Edwin van der Sar was between the sticks.
There might be something in the water in Bavaria, as Manuel Neuer also has a Champions League penalty to his name. However, his strike in the 2012 final against Chelsea was not enough to bring his team victory.
Naturally, the more dramatic goalkeeper goals aren't the ones which come from the spot, as Alisson showed with his match-winning contribution for Liverpool against West Bromwich Albion last season.
“I looked at my watch, 94, and I thought it was going to be the last kick of the game, we needed to win, so I shouted, ‘Get up, get in the box!’ to him!," Liverpool coach John Achterberg recalled after the Brazilian's match-winning moment.
"I didn’t see Ali looking to the bench to see if he should go up before I shouted; I just thought we had nothing to lose and we needed to put everything into the box we had.
