Starring: Robert Conrad, Dick Cangey, Ross Martin, Whitey Hughes
The Night of the Vicious Valentine - S2-E20
Revealing mistake: The red-headed villain falls face first into the wedding cake. The front of his face is covered with cake and icing. West "punches" him on the face - but punches are not real - that is why West has no cake or icing on the fist that "punched" the face covered with cake and icing. (00:46:30)
The Night of the Brain - S2-E21
Revealing mistake: Mr. Braine screams as his steam-powered chair crashes into the bandstand. If you look closely at the next shot, just before the explosion, you can see that the dummy now in the chair has its head bowed forward. It also has light brown hair, rather than Mr. Braine's silver hair. (00:47:10)
The Night of the Infernal Machine - S2-E14
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)
