When Samantha decides that her house needs painting, helpful Aunt Clara summons up the spirit of the best painter she knows: Leonardo Da Vinci (John Abbott). Trying to undo her misfire spell, Clara inadvertently places Darrin in a Renaissance costume, leading his newest client to mount an ad campaign using the image of the Mona Lisa. Naturally, Da Vinci is outraged at this desecration of his masterpiece, and it is up to Samantha to straighten things out. Written by Jerry Mayer and Paul L. Friedman, "Samantha's Da Vinci Dilemma" was first shown on December 28, 1967. ~ Hal Erickson, Rovi
