Shaq Walks Off Set After Charles Barkley Makes JAY-Z Joke

Last night, Kenny "The Jet" Smith compared himself to JAY-Z during some Inside The NBA hijinks.

"Probably not a good time right now," Charles Barkley said upon hearing Hov's name.

That cracked the studio up.

"You're silly," Smith said and eventually swithced the comp to Kendrick Lamar.

Shaq took it even further.  To conceal his laughter, he walked off the set.

JAY is being sued for raping a 13-year-old at a Puffy party back in 2000.

He denies the charge and has accused the alleged victim's lawyer, Tony Buzbee, of extorting him.
