An injured ACL is no laughing matter – but that didn't stop George Clooney
from taking a friendly jab at his fellow Golden Globe Awards nominee – who's also a fellow two-time
PEOPLE Sexiest Man Alive honoree – Brad Pitt
While introducing a clip from Pitt's film Moneyball
(the pals decided to introduce each other's films at Sunday night's ceremony, live from the Beverly Hilton Hotel), Clooney borrowed the actor's cane, which he is using as he recovers
from the slip that injured the ligament in his knee.
"I have to give it back to him," Clooney, 50, who walked the red carpet with girlfriend Stacy Keibler
, joked while using the black cane in jest. "He can't make it to the bar otherwise."
It's not the first time Clooney took a turn with Pitt's accessory: He posed
with Pitt's cane at Thursday's Critics' Choice Movie Awards.
"It wasn't life or death," Pitt, 48, previously said of his injury, which occurred when he slipped down a hill while carrying 3-year-old daughter Vivienne. "It was just an old man tripping."
Later in the show, Clooney called out his friend again, this time while accepting his best actor award for The Descendants
Speaking seriously, Clooney said it was "nice to see Brad and nice to be able to tell him not just what wonderful work he's been doing in two films this year, but in the rest of the world."
