Decades unwraps a Christmas gift of comedy in celebration of the comedic genius and enduring appeal of actress Carol Burnett. "A Christmas Carol" will feature selected episodes of Carol Burnett and Friends and The Lucy Show, alongside Burnett’s special guest host appearance in The Very Best of the Ed Sullivan Show.

This Decades presentation airs on Christmas day, Tuesday, December 25, beginning at 9a ET | 6a PT and continuing throughout the day.

"A Christmas Carol" features 27 of the most beloved and funniest episodes of Carol Burnett and Friends, presented in three blocks throughout the day. Featuring a famous cast of co-stars including Harvey Korman, Vicki Lawrence, Lyle Waggoner and later Tim Conway, the show aired from 1967 through 1978 for 279 episodes. During its legendary run, the series earned 25 Primetime Emmy Awards. Today it is considered among the greatest TV series of all time and remains highly influential to many comedic performers and TV series.

Featured sketches will include "Went with the Wind," "As the Stomach Turns," and "Tudball and Wiggins."

"A Christmas Carol" also presents Burnett’s four guest appearances on The Lucy Show with her real-life friend and mentor, Lucille Ball. The duo first met in 1959 when Burnett starred in the musical comedy Once Upon a Mattress, and their professional and personal relationship blossomed from there, with each appearing on the others’ television projects.

These charming episodes feature duets and routines by Ball and Burnett – including her famous Tarzan call.
