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."

Both actors are up for honors in the best actor in a drama category.?
