Gary Vinson took time off from appearing in McHale's Navy to appear in this episode.
Though all four regulars appear, Denny Miller and Terry Wilson don't show up until well into the episode.
Levy: So you're not afraid, David. Fine, but let papa be afraid for all of us.
McGowan: And here I was thinkin' you were a real gambler.
Hale: Gambler? Playin' this game with you is like puttin' money into a pocket with a hole in it.
Hale: That supper of yours tonight was almost edible, Charlie.
Wooster: Sure is a nice bunch of people along this trip. No troublemakers and no big problems.
Hale: So far, you mean.
Levy: Patrick McGowan as a relative! Please, David. I just finished eating breakfast.
