Charles Barkley roasts Celtics' Jayson Tatum on Stanley Cup Final telecast, gloats about relationship with Gary Bettman

Charles Barkley on Monday once again proved he is must-see TV, even (especially) when he's appearing on non-basketball broadcasts.

The TNT basketball analyst made an appearance on ABC as it broadcast Game 3 of the Stanley Cup Final, a 6-2 victory by the Lightning to shorten the Avalanche's series lead 2-1.

Oh, and Sir Charles had jokes — especially at the expense of Celtics forward Jayson Tatum.

During the first intermission on Game 3, Barkley was given the opportunity to break down the Lightning's go-ahead goal, which made the score 2-1. 

a turnover from Avalanche defenseman Devon Toews.

"Well this is a turnover, No. 1," Barkley said.

"This is a regular Jayson Tatum turnover.

I'm sorry, I'm just joking.

I love you Jayson Tatum, I'm just joking."
