As Grant Hill was driving to the hoop, he slipped, but the refs called a foul on Reggie Evans, who wanted a travel. Hill proceeded to give Evans a playful slap on the butt, Evans responded with his own slap, and Grant Hill had to get the last slap in, and it was the final straw for the ref who kicked them out! lol.
No hard feelings – they gave each other daps as they exited the game, both smiling while the crowd rained down boos on the referees.
