Other mistake: "Night of the Bubbling Death": When West lifts the unconscious bad guy by the shoulders and prepares to drag him out of sight, you can see drag marks already in the dirt from previous takes. (00:21:10)

1 other mistake in show generally
Starring: Robert Conrad, Dick Cangey, Ross Martin, Whitey Hughes
The Night Dr. Loveless Died - S3-E4
Continuity mistake: In the opening scene, a cowboy sitting atop the balcony above Big Brad's Bar gets up and approaches the balcony's edge twice.

Trivia: West collides with the cook and sends him sprawling face-down in a huge platter of gelatin. Before racing off again, West quips, "Sorry about that, chef!" This was a winking homage to the 60s spy comedy Get Smart and its bumbling hero Maxwell Smart's famous catch-phrase, "Sorry about that, Chief!" (00:47:30)
