S7·E11 The Corsican Cousins

Endora wonders why Samantha can't be more like Serena- spontaneous, free-willing, and loose. Endora puts a spell on Sam that makes her do exactly what Serena does. This causes problems for Darrin, especially when he has to deal with a all-business type client. Darrin is almost out of a job until Larry discovers that the client is linked to the underworld, and Darrin's job and sanity is saved again.
