"Day One at the Bar None"
In one scene where Mr. Ernst and melody are having a conversation, you can hear, faintly, talking. i'm not sure who it is or what its doing there but my guess is its the crew of the show (directors, producers, etc.) talking to each other when it was suppose to be edited out. see if you can find it.
During the episode, a reviewer from a well respected dude ranch publication is secretely evaluating the ranch. Well, when the special guest is revealed, it's not hard to notice but he is really Vic Vleck, from the competing Snake Eyes Ranch! OK, it's really the same actor, Paul R. Secrest, playing a different character.
In the episode where Brad and Melody are having a fight as bunkmates: There is a scene where Brad is trying to read and Melody is doing aerobics. As Melody gets more active and jumps around more you start to see a wire creep up around her neck. Another RF mic blooper.
While Brad lines up to hit the ball (while they play mini-golf) Ted tries to balance on his golf club and slides, almost falling.
