Be of good chair.

Actor Clint Eastwood got the idea to bring a chair onstage during his RNC speech last year from a Neil Diamond song.

The tune? "I Am... I Said," which includes the lyrics: “I am, I said, to no one there. And no one heard at all, not even the chair.”

Eastwood heard the song playing in his hotel room before delivering the address in August, CNBC’s Becky Quick reported Friday. She shared the detail, which Eastwood mentioned off-camera, after her interview with him aired on “Squawk Box.”

During the sit-down, Eastwood admitted that the speech — in which he pretended that President Barack Obama was sitting beside him — “seemed odd at the time.”

“But, you know, I'm an odd person," he said, adding that the backlash didn’t bother him.

"One thing about getting into the senior status of life, like I am, you don't really care,” he said. “You just say what you say and then you get away with it."
