Shaquille O'Neal, Charles Barkley, and the rest of the NBA on TNT crew got quite a surprise during their pregame show of Tuesday's Game 4 showdown between the Atlanta Hawks and the Milwaukee Bucks. Chuck came out with another one of his guarantees and it resulted in an epic appearance from none other than the Harlem Globetrotters.

As soon as Barkley hit his famed guarantee button, five members of the Globetrotters came out to the stage (h/t NBA on TNT on Twitter):

The entire crew was clearly excited by the surprise, but it was Ernie Johnson who had the best time. The Globetrotters decided to give EJ his own jersey as they officially named him as an honorary member of the squad.

For what it's worth, Barkley's guarantee was in favor of the shorthanded Atlanta Hawks. While he didn't exactly pick them to win in Game 4, he did say that he believes the Hawks will be able to cover the +9.5 spread the bookmakers have given them. Atlanta is the clear undergods in Game 5 with Trae Young being forced to sit out due to a bone bruise. Nonetheless, Charles Barkley believes that the Bucks won't be able to blow out the Hawks in this pivotal contest.
