Angus Duncan holds the distinction of being the very first boyfriend to Mary Richards in the very first episode of the Mary Tyler Moore show. He's the reason Mary moves to Minneaoplis in the first place. After two years of supporting "BILL" while he works his way through residency he finally becomes a doctor and then "BILL" declares 'Why rush into marriage'. So she high tails it out of town. Later in the episode he shows up but struggles saying the words 'I love you' and Mary tells him goodbye. But not to worry, gosh darn it, she's gonna make it after all.
