Boston Celtics point guard Kemba Walker had a hilarious reaction to Toronto Raptors All-Star Kyle Lowry arguing a foul call in Game 3 on Thursday.

As you can see, Kemba Walker has no idea what Kyle Lowry is arguing about. Luckily for fans, the cameras caught his epic reaction.

Walker and the Celtics are up 2-0 on Lowry and the Raptors. If the Celtics win Game 3, the series is over, as no team has ever erased a 3-0 deficit in the playoffs.

Walker has been a great addition for the Celtics after Boston lost Kyrie Irving to the Brooklyn Nets. It's great to see Walker play in the postseason since he's one of the best guards in the NBA and didn't get to shine on the playoff stage with the Charlotte Hornets since the team was putrid.
