In his home, actors Lee Si Un and Nam Goong Min can be seen sitting around a table when out of the blue, Lee Si Un asks, "Where's Guam?" to which Nam Goong Min angelically answers, "Next to Indonesia?" Resulting in the two laughing, the geography questions did not stop there, for Lee Si Eon asks, "Who owns Guam?" to which Nam Goong Min confidently states, "For sure, Southeast Asia." This brings Lee Si Un into puzzlement, and while facing the map on the wall, he asks Nam Goong Min the question again, leading him to second guess himself.
The actor tries to save face by expressing his frustration with tests which ask about the minor details and explains his strong suit is actually in English, not Geography.
