Welcome Back, Kotter ran on ABC from 1975-1979. It featured Gabe Kotter, a wise-cracking teacher who returns to his high school alma mater - the fictional James Buchanan High in Brooklyn, New York - to teach an often unruly group of remedial wiseguys known as the "Sweathogs." The school's principal, Mr. Woodman, dismissed them as worthless hoodlums and only expected Kotter to attempt to control them until they inevitably dropped out. Recognizing that he is those students' last chance to have a decent enough education to allow them to survive beyond school, he soon befriends them while they learn to recognize and appreciate his commitment to them. This extended to his students often visiting his Bensonhurst apartment, sometimes to the chagrin of his wife, Julie.
