As the series progressed, it focused more on Fred's antics and schemes, with Lamont often adopting the role of the gentler, more open-minded progressive who attempts to broaden his father's horizons. It closely mirrored the relationship between Archie and Mike on "All in the Family". A notable example of the softening of Lamont's character is his change in attitude towards Donna Harris (Lynn Hamilton), Fred's girlfriend. Early in the show's run, Lamont derides her as "the barracuda" and is openly hostile towards her, attempting to ruin her relationship with his father at least twice, but in a later episode he invites her to dinner with his own girlfriend, remarking that it would do his reputation good to be seen with "two lovely ladies."
