This episode is Ward\'s experimentation with British humor, substituting \"geezer\" and \"geiser\" and then working the story line around this plot twist. Ward had to stretch reality a bit farther than ordinary in this episode however. The geiser is shown to be nothing more than a large rock with a hole which the geezer easily carrys away. If one can ignore this nonsence, the plot is actually rather enjoyable.
BTW: the geezer is also remarkably well preserved for an individual who must have been at least 100 years old.
