Samantha is invited to paint a picture for a charity exhibit. Dissatisfied with the results, Endora secretly switches the painting with a genuine Monet masterpiece, affixing Sam's signature to the work of art. Trouble begins brewing when Sam wins first prize -- and Darrin's client, Mr. Cunningham (Arthur Julian), insists upon purchasing the painting. Written by Jack Sher, "Art for Sam's Sake" first aired on February 23, 1967. ~ Hal Erickson, Rovi
