Part of what makes TNT's Inside the NBA so entertaining is you just never know what to expect during interactions between Shaquille O'Neal and Charles Barkley.
Thursday night delivered yet another prime example of that dynamic between the NBA Hall of Famers.
When a viewer compared the crossover that Denver Nuggets guard Jamal Murray hit Oklahoma City Thunder center Steven Adams with to the notorious fight that the Diesel and Sir Charles had on the court in 1999, Shaq decided to add some emphasis by whispering to Barkley "I'll knock your ass up" on live TV.
Catch the hilarious moment just past the 1:45 mark of the video below.
Shaq hilariously threatening Chuck live on Inside the NBA isn't anything new, either. Last May, the four-time NBA champion vowed to punch Barkley in the face when an argument between the two got heated.
He got closer than arm's reach to repeat much of the same last December.
And there were times when things between the two got physical as well, like this time O'Neal took Barkley down MMA style.
Of course, their on-air exchanges are consistent with the time they scrapped for real in 1999 on the hardwood.
Never change, guys!
But for real, though, Chuck ... don't cross that line with the big fella.
