*Message to Kenny “The Jet” Smith: Shaq is gonna get you. It’s only a matter of time.

Actually Mr. Smith already knows that. He says he’s constantly looking over his shoulder — waiting for Shaq to try to get his revenge for that infamous Christmas tree shoving.

If you missed it, Smith tossed Shaq into a tree on the set of “Inside the NBA” … leaving the Big Fella flat on his ass covered in broken branches. And yes, it was hella funny, too. (Watch it below.)

“I thought it would be funny … but I didn’t know it was gonna be THAT funny,” Smith said.

As for Shaq’s revenge, Kenny told TMZ Sports that he knows it’s coming — it’s just a matter of time.
