Bewitched

A year after Aunt Clara passed on, Esmerelda carries on her memory by being a bumbling witch as well. Esmerelda sneezes up a whole lot of trouble when Darrin has a prospective client over to look at ad layouts. Then, when she gets nervous, she fades out. Darrin uses Esmerelda's magical snafus to good use when he presents a unicorn as a design for the client's car company. Samantha tells Darrin that Esmerelda will only visit when she is called.
