Jimmy Fallon -- Jay Leno Won't Jack My Job


Jimmy Fallon's pretty confident ... history won't repeat itself with Jay Leno angling to re-capture his "Tonight Show" gig.

We got Jimmy at LAX Friday night ... he has no fear of ending up on cable -- like Conan O'Brien.  Of course you remember when Jay was 86d the first time around ... he schemed for his job back and NBC obliged after having a serious cases of buyer's remorse.

Jimmy's show fires up after the Olympics ... and the big advantage he has over Conan ... Jay won't sink the ship at 10P.
