ST. PETERSBURG — Paper covers rock. Scissors cut paper. Rock crushes scissors.

If you remembered that as a kid, and somehow mastered it as an adult, you could earn some quick cash.

The childhood favorite gets an adult twist on Thursday night when SubCentral, the downstairs bar at The Iberian Rooster on Central Avenue, hosts its first ever Rock Paper Scissors Competition.

"It's inspired by the owner of Iberian Rooster, Russell Andrade, who actually competed in a national rock, paper, scissors competition a few years ago," Lauren Lance, entertainment coordinator at Iberian Rooster said. "We have several judges, and there will be commentary. We're running it in the spirit of UFC, it will be pretty crazy."

The St. Petersburg speakeasy style bar, at 475 Central Ave., Suite 100, is offering a winner-take-all prize of $100 to the winner, according to a post on the group's Facebook page.

The competition runs from 9 p.m. until around 2 a.m.
