The Carson City mint is broken into and the plates stolen, replaced with inferior copies. After various attempts on their lives the agents manage to focus their suspicions on Warren Trevor, big game hunter and circus proprietor, who is hoping to purchase a large tract of land in Africa.
Tropes present in this episode:
- Counterfeit Cash: By the time Jim and Artie recover the stolen plates, stacks of bills have already been struck from them. Jim takes the plates and makes a run for it while Artie stays behind to burn the piles.
- Hairpin Lockpick: Jim purposely leaves Artie locked in a cage at episode's end. Artie reaches through the bars, plucks a hairpin from the head of a girl nearby and frees himself.
- Knockout Gas: Gas pumped in from a gaslight lamp and an unspecified additive is used to fill a very large U.S. Mint set and knock out several people within seconds.
- Laughing Mad: Cosette, the lovely ballerina who lures Jim into the trap below, who laughs insanely at the thought of seeing him get munched. (She's very disappointed when he isn't.)
- Never Smile at a Crocodile: While investigating the circus grounds, Jim ends up in a lake. Enter one large and apparently hungry crocodile. A few minutes (and one commercial break) later, exit James West... from the lake, leaving the crocodile dead behind him.
- Non-Ironic Clown: This is Artie's disguise of choice when he infiltrates the circus, complete with elaborate makeup, baggy costume and cheerful, playful miming.
- Tampering with Food and Drink: Jim and Artie are about to down a couple of drinks in a restaurant when they notice a distinctive odor coming from the glasses.
- Throw the Dog a Bone: The first three episodes of the series ended with Artie looking on resignedly while Jim made out with the Girl of the Week. In this episode there are two girls... and Artie walks off with both of them, one on each arm (see the upper right corner of the page image).
