It is revealed in this episode that Ed has a daughter. This was her only appearance on the show.
Bill Dana was the writer for this episode. In #1.18;"Sammy Stops In," the story is very similar to a segment of All In The Family, #2.21;"Sammy"s Visit," in 1972, which Dana wrote. Though Dana is not credited as a writer for the Chico and The Man story with Sammy, the similarities are hard to ignore.
