Maggie (Joanna Kerns) is worried when Mike (Kirk Cameron) begins obsessing over a girl named Lisa (Dana Plato). It isn't that Mike is all that fond of Lisa; it's simply that she is an exact (and deliberate) lookalike of pop star Madonna), right down to wearing the "Like a Virgin" wedding gown! Meanwhile, Carol (Tracey Gold) tries talking to plants to see if the conversation will have any effect on their growth. ~ Hal Erickson, Rovi
