Fred Rogers on Letterman, February 17, 1982

Fred Rogers' only appearance on the 11th episode of LNwDL.
There have been a lot of comments here complaining about the lack of time Rogers had. I've tried to explain that on this particular show, Rogers was the third guest. The first two were Julie Andrews and Andy Kaufman. Blame the producer if you must, but there was simply little time left for Rogers; the show couldn't run longer than its allotted network time.
