Everyone knows Shaquille O'Neal has a great sense of humor, and he showcased that in full during a recent broadcast of Inside the NBA - however, did he take things a bit too far?  While discussing players talking to refs about issues during games, Charles Barkley recalled his time on the court and how he would verbally interact with the referees.  This prompted Shaq to interject by stating, "You used to kiss up to them."  

Charles denied Shaq's claim to be true, which then opened a door for Shaq to throw some comical jabs at Charles.

"You kissed d*ck in the mouth," Shaq said, referring to referee Richard T. "Dick" Bavetta.  After everyone burst out laughing, Shaq eventually repeated the comically suspect phrase two more times.  It was all pretty humorous as Shaq couldn't even contain his own laughter.
