 One of the implied humorous points of the show is that Thurston continually fails to realize that all of the Howells' money is essentially useless to them on the island.On the other hand, the other castaways apparently tolerate the fact that he refuses to do any work.One exception is when an egocentric Hollywood producer (played by Phil Silvers) "visited" the island and the Howells had to wait on him as butler and maid in order to be rescued.
