In "The Night of the Bottomless Pit," Artie is locked in a room with two very large men who are his competition for the job of prison guard. He disposes of them rather quickly and spends the next minute or so pretending that a knock-down, drag-out fight is going on, with appropriate sound effects, all for the benefit of the villains outside. When he decides that he's impressed them sufficiently, he casually knocks on the door to be let out again.

The ongoing feud between Artie and the Sicilian chef in "The Night of the Infernal Machine."
From "The Night of the Colonel's Ghost":
(Jim and Sir Ian Gellico Cooper-Featherstone [Artie in disguise as an English big game hunter] are about to leave a room) Voice behind them: Rawk! Fraud! Fraud! Brawk! ("Sir Ian" freezes, then whips around in surprise... to see a parrot in a cage) Parrot: Brawk! Rawk! Fraud! "Sir Ian": (offended) Vulgar feathered American.
