Devices: Gun with harpoon line, acid pellet in boot heel
Disguises: none (neither Artie or any other disguise expert appear)
Jim rides into town wearing chaps and dismounts. He walks down the street and the chaps have disappeared.
The opening scene in the teaser of this episode is the same scene in the opening of act 1 with the same two women crossing the street. The scene in act 1 is a little earlier than the teaser scene before the women appear onscreen.
Robert Conrad got a haircut during this episode, and in the opening scene in the boardroom, his hair is obviously shorter from one camera angle to another. It looks better shorter.
A blooper occurs at the end of the third act where the animated bumper doesn't move until after the words "The Wild Wild West" appear. In every other commercial break in the series the title appears only over a still image.
Jim: I'm just naturally suspicious when a monkey attends a board meeting, gentlemen.
