WKRP was one of the greatest sitcoms of all-time. One of the best scenes in the series is Venus Flytrap (the overnight soul DJ) dropping some science on this gangbanger. Venus had befriended his mother, who was a cleaner at the radio station, and she was worried her son was dropping out of school.
The scene you don't see, after the end of the clip, is Venus breathing a huge sigh of relief after the kid leaves that he's still in one piece. Even better, Johnny Fever (the morning rock DJ) wakes up from a pile of boxes across the room complimenting Venus' teaching abilities.
Who says you needed Schoolhouse Rock to learn in the 70s? Venus was da man!
