Veteran screen sourpuss Charles Lane is cast to perfection as Darrin's new client, J.W. Mortimer, a crabby soup tycoon. As Samantha tries to convey the spirit of Christmas to the truculent Mortimer, the episode subtly morphs into a modern-day Christmas Carol, replete with Bob Cratchit and Tiny Tim counterparts. Even Santa Claus makes a special guest appearance, in the form of chubby character actor Don Beddoe. Written by Lila Garrett and Bernie Kahn, "Humbug Not to Be Spoken Here" originally aired on December 21, 1967. ~ Hal Erickson, Rovi
