Grant Williams chose to celebrate Father’s Day very fittingly on Sunday.

Williams, the former Tennessee star and current Boston Celtics forward, took to Twitter to troll his old SEC rival school Vanderbilt with a hilarious tweet implying that he was their father. Take a look:

Williams, 21, who spent three seasons with the Volunteers, was famous for the headaches that he gave the Commodores during his college career. Williams twice set career-highs against Vanderbilt, scoring 37 points against the Commodores in 2018 followed by a 43-point outburst against them in 2019.

Even in the NBA, Williams continues to live rent-free in his opponents’ heads, and Sunday’s tweet was an indication of what makes him a truly great troll.
