S1, E35: Samantha and Endora discover the culinary delights of Mario's restaurant. Mario tells them he is going broke because he refuses to sell pizza. Samantha learns that Darrin's agency has a new client, Linton Baldwin, the owner of a large chain of pizza parlors. When Samantha uses witchcraft to get a huge newspaper ad for Mario, and Endora inserts a plug for him on Baldwin's TV program, Baldwin tells Larry Tate he is cancelling his account and signing with the agency handling Mario's restaurant. Realizing Darrin's career is in jeopardy, Samantha persuades Endora to help save the Baldwin account for Darrin. They lay out a spectacular advertising campaign for Baldwin and give the credit to Darrin's agency. Not only does Baldwin ask Darrin's agency to keep his account, but Mario's restaurant becomes a great success.
