Sprinkled here and there in all three games. The best is probably the Funny Background Event in a cutscene in Hell's Highway where Paddock finally reaches the end of his patience with his chronically-broke-down jeep, announces his intention to "put the bitch out of her misery" and tries to shoot it while other Recon Squad paratroopers try to stop him.
In "Operation Garden", the player meets Redwood from the Irish Guards who, despite Hartsock and Doyle speaking normally, has a thick sterotypical Irish accent and hands Baker a drum magazine Thompson while saying "It's Jesus resurrected compared to your Yank Tommy!".
