In what appears to be a spectacularly low act, a man in a private box poured beer on Sydney Kings superstar Marcus Thornton while he was playing.
And what's worse, it was a tinnie of light.
The incident happened on Wednesday night during the third quarter of a grudge match against the Kings and the Illawarra Hawks at WIN Sports and Entertainment Centre in Wollongong.
Points to American player Thornton for keeping his cool in the face of such a grub act.
After the game, won by the Hawks, Thornton told Fox Sports: “It’s unfortunate, but it is what it is and we move on.”
People on Twitter haven't been so kind, with people calling for him to be slapped with a life ban.
