Synopsis by Hal Erickson
Carol Burnett makes her first Lucy Show appearance as Carol Bradford, a meek, frumpy librarian who has become the new roommate of Lucy Carmichael (Lucille Ball). Hoping to get the timid Carol out of her shell, Lucy and Mary Jane (Mary Jane Croft) throw a party for the girl, replete with such guests as The Vagabonds, a musical group (and yes, that's an unbilled Joe Pesci as one of the performers!) Unwittingly, Carol drinks a wee bit too much at the party, and as a result sheds her inhibitions (and some of her clothes!) with a boisterous performance of "Hard-Hearted Hannah."
