Grundy is a British television sitcom starring Harry H. Corbett as puritanical newsagent Leonard Grundy who, after a divorce, opposes the idea of a 'permissive society' and befriends the wife of the man who left with his wife.

It was initially scheduled for late 1979, but a ten-week industrial dispute and a subsequent heart attack by Corbett caused broadcast to be postponed until 1980.
