Celtic are chasing an unbeaten season and a 100 point total after coasting the top-flight of Scottish football this season, but the side closest to them over the past nine months or so has been Aberdeen.
It had been expected that Johnny Hayes, Adam Rooney & co. would provide a tough test at Pittodrie, as they would take joy in spoiling Celtic's ongoing party, but that idea was dismissed extremely quickly as the visitors found themselves ahead after just three minutes in what would prove to be a blistering start.
Former Man City defender Dedryck Boyata scored for the second game in succession, and Celtic smelled blood.
Next to get in on the act was Stuart Armstrong who captialised after Leigh Griffiths bamboozled the Aberdeen defence out on the right wing.
A piss-taking nutmeg if ever there was one.
And the Abdereen fans could have been forgiven for heading for the exit after just 11 minutes, as the game was totally killed as a contest.
Griffiths, who had a hand in the opening two goals, got his goal with a cracking striker from distance.
But then Ireland international Johnny Hayes hit back, showing that Aberdeen were not simply going to roll over and let Celtic hammer them.
It was a lovely strike from Hayes, the pick of the bunch. Thankfully no Aberdeen fans did elect to pack it in, although they wouldn't have gotten far if they did.
We say pick of the bunch, but we really mean so far because for all we know there could be another 20 goals in this game.
Leigh Griffiths is on fire.
