Nikola Jokic greeted Luka Doncic before the Lakers faced the Nuggets, then gave his friend an unexpected pinch as Luka headed back toward the Lakers’ bench. Doncic kept a straight face and didn’t visibly react, making the playful moment even funnier.

The exchange looked like the kind of inside joke shared between close friends. The NBA has highlighted Nikola and Luka’s friendship and prankster moments before.

The moment happened before the teams’ preseason finale on Friday, Oct. 16. Denver beat Los Angeles 121-106; Doncic scored 15 points in 18 minutes, playing only the first half.
