The accent is on the holiday season when Carol Burnett's old friends Garry Moore and Durward Kirby drop in for their annual visit. Carol and Harvey play the old folks as they reminisce about their marriage. Moore and Kirby play opposing attorneys in the courtroom trial of Mrs. Peter Piper, whose husband picked a peck of pickled peppers. Miss Burnett recites an original Christmas poem and solos "Make Your Own Kind of Music" and later joins the Bob Mitchell Boys Choir in singing "Do You Know How Christmas Trees Are Grown?" Garry Moore assists Durward Kirby in delivering some "commercials" merchandising gifts for kids. In the "Carol and Sis" sketch, Carol throws a tantrum when husband Korman hosts his poker club.
