Step by Step S05E10 - Baby Come Back

Dana was eager to see 'the Amazing Codini' perform, but realizes too late he takes her into the magic box, hasn't fixed the necessary link to get out again and has no back-up plan, even knocks it over- they are trapped indefinitely, to her absolute horror, while he enjoys the closeness; yet salvation is within reach all the time... Meanwhile Carol dragged Frank to a beauty convention (a fake temperature doesn't fool experienced parents), then told him to entertain himself as she couldn't interest him in the least, only to finds Frank enjoying a female participator's manual hair-care too much... Reading about a cash price for the baby chosen at a Yum-Yum baby-food commercial audition, Lilly's babysitters J.T. and Al dashed off thereto but are too excited. When their parents return, Lilly has been switched with a baby-boy.
