Not even the 2017 Oscars could result in a truce between these two Hollywood stars.
What came next was a new chapter in this famous—and dare we say hilarious—feud.
"Tonight, in spirit of healing and bringing people together, I would like to bury the hatchet with someone I've had issues with. I would. Matt Damon," Jimmy began during his opening monologue. "I've known Matt for a long time now. I've known Matt so long, when I first met Matt, I was the fat one, okay? It's true. And we've had problems. He's a selfish person. Those of you who have worked with him know this. But Matt did something very unselfish and I want to commend him for it."
He began to share how Matt allowed Casey Affleck to star in Manchester by the Sea, which ultimately became an Oscar-nominated performance.
"He handed an Oscar-caliber role over to his friend and made a Chinese pony tail movie instead," Jimmy joked. "And that movie went on to lose $80 million. Smooth move, dumb ass. See? It's so easy to reach out and heal."
