In this crazy episode, Samantha gets a condition which makes her entirely 500 pounds heavier. Dr. Bombay comes and gives her an antidote that makes her lighter…a little too light as she floats to the air! This will be hard to hide when the Prescotts, McMann and Tate’s newest clients, has Samantha volunteer for a charity bazaar and fashion show. Sam tries everything to help weigh her down, but to no avail. In a memorable scene, Samantha holds a giant urn on her shoulder as she goes down the runway half floating, half walking in the fashion show. It is there that Darrin comes up with a spectacular slogan for Prescott shoes.
