Donna Harris (Lynn Hamilton) is Fred's on-again, off-again girlfriend who later becomes his fiancée. She is employed as a practical nurse. Donna is an amiable, even-tempered lady who takes in stride Fred's shenanigans and occasional trysts. She also appears to be more sophisticated in contrast to Fred's rather blunt and boorish personality. Lamont, being the overprotective son, mistrusts Donna at first (branding her as "The Barracuda"), but by Season 6 has completely warmed to her. Esther is hostile toward Donna at first, almost coming to blows with her during their first meeting on Donna's and Fred's wedding day (an event that causes the cancellation of the wedding). Eventually, Esther warms to her as well.
