21 Jump Street: Season 3 (1988-1989)

Young L.A. cops go undercover in high schools in this teen-oriented police drama, which helped jump-start the new Fox network in 1987. It was the network's most-watched show that first year, and Booker became an insurance investigator who spun off to his own short-lived series. The title, incidentally, is the address of the unit's station house, a converted chapel.
