Shaquille O'Neal -- 'Wanna See Me Smack Kenny Smith In the Head?'

We ran into Shaquille O'Neal for 84 seconds in New York City Monday ... and here's what happened:

1) He spoke Hebrew to us
2) He insulted Batman
3) He named the BEST movie he ever appeared in (Hint: It's not "Kazaam")
4) He sneak-attacked Kenny "The Jet" Smith and slapped him in the back of the head.

Again, just 84 seconds ... but it's hilarious.

BTW -- Kenny has now threatened to sue Shaq for $100 million ... so, stay tuned on that one.
