Bud refers to his grandfather as "Tutu Kane", which is Grandpa in Hawaiian.
Frank Silvera was borrowed from NBC's "The High Chaparral," where he played the patriarch of the Montoya ranching family, to appear in this episode, which was filmed before "Chaparral" started work on its abbreviated fourth season. Silvera died in a household accident just after returning from Hawaii, and this episode was postponed until after Christmas (Silvera's character in The High Chaparral, Don Sebastian Montoya, was not mentioned in the series until a two-hour special in February 1971 dealing with his funeral).
The title means a Hawaiian cowboy, the paniolo, a descendant of the vaquero of California and Mexico.
