This week's Throwback Thursday classic goal - sponsored by The World of Cars - is Alan Biley's famous 'Santa Time' winner against Oxford United on 22nd December 1984.
Pompey had been 1-0 down at 90 minutes, in a typically dreadful December day's weather at Fratton Park.
Following an earlier run-on from a man dressed in full Father Christmas attire, a hefty amount of stoppage time had been tagged on.
And Biley struck twice in the added period - since coined 'Santa Time' due to the nature of the stoppage - to provide The Blues with a last-gasp, scarcely-believable victory.
Biley's first - the equaliser - was also a header, coming after Neil Webb's centre was nodded in at the near post.
And this goal - the winner - came as a result of Mick Kennedy's corner at the latest possible stage.
Cue an almighty euphoric roar from the Fratton faithful, in response to a bizarre Pompey moment that would go down in folklore.
