While performing his studio duties for CBS during last night’s NCAA tournament games, Charles Barkley became the recipient of a playful Shaquille O’Neal tweet that Greg Gumbel read on air. Chuck, who works alongside Shaq on TNT’s ‘Inside the NBA’ studio show, responded by going on a hilarious rant about Shaq’s level of education, his endorsement deals, and the comparison of their bank accounts. Just another example of why Chuck is the greatest.
