Charles Barkley was targeted with yet another prank on the "NBA on TNT" set on Tuesday ... this time, the Hall of Famer was victim to a Halloween-themed smoke attack!!
The Chuckster was at his usual spot on the desk alongside Shaquille O'Neal, Kenny Smith and Ernie Johnson as he weighed in on the New York Knicks ... when out of nowhere, his area started to fill with fog.
Barkley's analysis was quickly derailed .
