David Letterman Walks Out on Joan Rivers Interview (Video)
David Letterman has given Joan Rivers a taste of her own medicine.
Letterman (in jest) walked out during the middle of his The Late Show interview with Rivers Tuesday, just days after she abruptly left a CNN interview.
Rivers earlier told Letterman that the interviewer had been "judgmental," "nasty" and "opinionated."
"It was just like my wedding night," she said.
