Get Smart - 4x19 - Absorb the Greek

Max and 99 have been ordered from higher up to tail the Chief based on his recent behaviour. The Chief goes to a computer dating service, and shortly thereafter begins to date a young Greek girl. However, the Chief is under deep cover, as the girl is the wife of scientist Dr. Paponickolini and she is using her "dates" with the Chief to pass information to him about the findings of her husband, who is working on a "fountain of youth" formula.
