Commentator Tommy Heinsohn is famous for his lack of impartiality when offering colour analysis on Boston Celtics' games.
That favouritism reared its ugly head with hilarious results in the Celtics' 109-102 loss to the Chicago bulls last night.
This Vine shows the aftermath of the referee's offensive foul call on Jared Sullinger that Heinsohn found "TERRIBLE".
It's far from an isolated incident as you can tell from this compilation of Heinsohn's partisanship.
