"The will be my last time on the David Letterman show, I understand," an emotional Macdonald said as he transitioned into a story about the first time he saw Letterman perform.

"Mr. Letterman is not for the mawkish, and he has no truck for the sentimental," Macdonald said. "If something is true, it is not sentimental. And I saw in truth, I love you."

Letterman's response — "That was very sweet, Norm," he said, with a pat on the back, and a hug.


Letterman's final episode will air May 20 on CBS with guests Tom Hanks, Eddie Vedder and Bill Murray.
