"The Lucille Ball Special: Lucy Calls the President" - November 21, 1977

 Housewife Lucy Whittaker is concerned about local (Indiana) civic affairs and places a call to President Jimmy Carter.  Much to her surprise the president agrees to stop by her house for dinner and discuss it with her while he is visiting the area.  Once the word gets out everyone Lucy knows wants an invitation.

Fun Fact:

This special featured the final time that Lucille Ball (1911-1989) would work with her long time friends and co-stars including Mary Jane Croft (1916-1999) and Mary Wickes (1910-1995).  The most significant fact is that this is the final time Lucille Ball and Vivian Vance (1909-1979) work together.  During this special Vance is already suffering from the cancer that would cause her death two years later.
