Then, in a moment that’s now going viral online, he donned the jersey and showed off the catchphrase to the camera, complete with a kung fu high kick.
“Yo, what’s up? I’m Jack Black and I’m here to say, Up the Wahs!” he declared.
Though it appears his fandom has lasted only a few days. Black was in Sydney this week continuing his promotional work where the Penrith Panthers pounced.
The NRL defending champions shared photos on X with Black wearing a Panthers jersey with “Dragon Warrior” on the back.
The Warriors and Panthers don’t clash until May 19, giving Black a few months to make his choice.
