Shaq -- Accidentally Plays N-Bomb Song ... During 'Inside the NBA'

Record scratch moment for DJ Shaquille O'Neal last night -- when the Big Fella spun a track laden with the N-bomb ... and it AIRED during the live broadcast of "Inside the NBA."

Ernie Johnson and the gang were signing off when they threw to Shaq to play them out with a music track. FYI -- Shaq was performing in front of a HUGE live audience from a DJ booth and was away from the broadcast table.

But as the crowd went wild, Shaq decided to play a version of Jay Z's "Tom Ford" ... complete with several unbleeped n-bombs ... apparently unaware that he was live on the air.

It appears the broadcast dipped to black early once producers realized what was happening.
