You won't like Al Horford when he's angry.

Giannis Antetokounmpo learned that the hard way in what was a wild Game 4 between the Boston Celtics and Milwaukee Bucks. It all started when the two-time MVP threw down a dunk and stared down Horford early in the third quarter.

Antetokounmpo received a technical foul for the staredown, but that wasn't his only punishment. Horford got him back in the fourth quarter with an emphatic dunk of his own. The 35-year-old scored 16 of his 30 points in the final frame to lead Boston to a 116-108 victory.
