Scarlett Johansson shouldn't quit her day job.

After Al Roker was sidelined with laryngitis this morning on "Today," the sexy "Hitchcock" star (wearing Dana Rebecca Designs and Graziela jewelry) tried filling in.

"I'd say this is my dream come true doing the weather with Al Roker," Scarlett said before attempting to do his job.

While she did O.K. reading Roker's script, she had a little trouble when it came to finding U.S. locations on the map ... specifically the entire state of Pennsylvania.

Sure, ScarJo did an admiral job, but when it comes to celeb weather girls, Coco Austin is still the winner.
