A sit-com trio

Most of the one-off characters in The Mary Tyler Moore Show are played by actors who are, for me at least, unrecognizable. But there are exceptions. Three familiar faces appear in the episode “His Two Right Arms” (March 4, 1972).

[Bill Daily as Pete Peterson, a hapless city councilperson.]

[Isabel Sanford as Mrs. Wilson, mother of Peterson’s aide.]

[Davis Roberts as a citizen asking a question.]

Daily and Sanford should be immediately recognizable to anyone of a certain age who’s spent time in front of a television. Roberts might be less recognizable: he appeared in Sanford and Son as Dr. Caldwell, the cigarette-smoking “doctor” who works in the post office. Catchphrase: “I don’t know.”

Familiar faces in new arrangements: one of the pleasures of television.
