Spacey appeared on "Jimmy Kimmel Live" on Mar. 2 after Ford did a brief cameo on the show a day before his scheduled interview.
"That's the first time I've had to follow a Ford," Spacey quipped. "And one that was so banged up."
Ford has been under great pressure to resign since he admitted smoking crack last year, and several videos have emerged that showed him seemingly drunk or high.
Ford made the comment about Spacey on his show on YouTube, "Ford Nation."
