In the spirit of Halloween, Boston Celtics forward Grant Williams conducted his postgame media availability in a Batman costume after his team's 112-94 win over the Washington Wizards on Sunday night.
In the background of the clip, Celtics star Jayson Tatum can be heard asking Williams, 'What the f--- are you doing?' much to the delight of the reporters.
Williams arrived at the stadium in the same Batman costume.
The Celtics moved to 4-2 after the win. They get a few days off before playing the Cleveland Cavaliers on Wednesday. Williams wasn't required to save the day with a heroic performance but had a respectable 10 points in 24 minutes.
