These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Guard
Acceptable Targets: Dubliners are pretty much made fun of by most characters. Including in one scene where one character asks why Gerry is fiddling with his crotch, Gerry explains that he was after sleeping with two Dublin prostitutes.
Gerry getting dressed into his best uniform at the end and closing the wardrobe. The audience is greeted to Gerry armed with a Kalashnikov.
Same Circumstances Different Reasons: In one scene, a person is stopped by Gerry. The person proceeds to talk in Irish, and Gerry lets him off, not knowing that in Ireland everybody speaks English, in every area. Irish find it funny for that reason, Americans would find it funny for the cultural difference.
