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.

Endora says that Darrin is pig-headed and proves that by blinking a pig's head on his body! This is a catastophe for Darrin, but turns out to be a great ad campaign for his new client.
