It got extra nasty between Shaquille O’Neal and Charles Barkley during “Inside the NBA” on Tuesday night.

This isn’t the first time the two have exchanged heated words, but without normal host Ernie Johnson on the desk, it went to another level.

It all kicked off when Barkley stated that Toronto Raptors coach Dwane Casey owes his All-Star guard DeMar DeRozan an apology for benching him in Game 3 against the Cavaliers.

O’Neal thoroughly disputed the claim and used his own personal experiences to argue that a star player and their coach don’t need to see eye to eye to claim the ultimate success.

Barkley: “He needs to repair his relationship with DeMar DeRozan.”

O’Neal: “No he don’t.”

Barkley: “Uh, yes he does.”

O’Neal: “No he doesn’t.”

As the exchange continued and began to gather steam, fellow panelist and former player Kenny Smith sat back watching the duo throw haymakers.

The two continued their argument about DeRozan and Casey before turning to their favorite topic: how many times each of them made it to the NBA Finals.

“Me and Pat Riley never saw eye to eye and what happened,” O’Neal said with a raised voice. “You don’t know what you’re talking about when it comes to championships. Stop babying these players, you got babied and that’s why you ain’t win.”

Barkley then retreated to an old comeback he’s used against O’Neal on several occasions.

“I didn’t have Dwayne Wade and Kobe Bryant carrying me up and down the court,” Barkley said.

It was then that O’Neal stepped up to the line and nailed Barkley with a brutal takedown.

“I’ve got three finals MVPs, Google me, Chuck. Google me,” O’Neal snapped back. “You see that (pointing to his championship ring), Google me.”

After all of that, Smith finally decided to interject.

This isn’t the first time Barkley has been called out for his comments during the second round of the NBA Playoffs.

He caught the ire of Warriors superstar Draymond Green after proclaiming he wanted someone to “punch him in the face.”

Green bit back by proclaiming in his post-game press conference he’d welcome Barkley to back up his words.

“If you feel that strongly about it, then punch me in my face when you see me,” Green said.

Barkley ultimately apologized.
