Ginseng says: "Today I will show you my revolution"
"It's very great and important. Therefore you had better open wide your eyes and see it carefully"
(Then Ginseng shows his new earings)
Ribbon Ginseng thinks : " DON'T....DON'T.... LAUGH" (He tries not to laugh at Ginseng's face)
The last conversation which Ribbon Ginseng, Liberty and Robot participate in means:
Ginseng says: "Hi..."
Liberty (talks with Robot): "Oh my god, did you really need to do that harshly?" (Liberty thinks that Robot did hit Ginseng so badly, therefore Ginseng's face becomes like that).
Robot: "Why does this have to be related with me? I went out with you for the whole day yesterday!"
The whole story implies the recent event in Northern Korea. The president of Northern Korea, Kim Jong il, has decreed that Northern Korean women can wear earings and pants (they could only wear long dress and no earings in the past). Northern Korea sees this event like a very huge and progressing event. However, with a morden country where people dress very fashionably like South Korea, this event sounds like a big joke.
And the reason why Liberty blame Robot for Ribbon Ginseng's injury is Japan (robot) and South Korea (Ribbon Ginseng) are having some conflict about an island named Dokdo (or Takeshima). So Liberty thinks that Robot must have gone nuts through their quarrel and hit Ribbon Ginseng in his face.
