Basketball fans are usually not the rowdiest of folks.

On Wednesday night, a fan was seen pouring a beer on the face of Sydney Kings star Marcus Thornton during a game between the Kings and Illawarra Hawks.

Thornton was seen sliding off the court, before the fan poured beer from his can onto the American. Somehow, the 22-year-old was able to control himself and not react to the idiotic fan.

The fan was escorted from the Arena after the incident with his wife. The Hawks won the game 96-90
