Waah, it’s the Greek army!
[T/N: The file name of the first picture is “Nihonihosan to ameneko”, or something like “Japa-Japa-san and Americat”. It doesn’t sound offensive in Japanese, though. =A= The second one’s file name is also “Waah, it’s the Greek army”.
By the way, that appears to be a reference to one of his “Punchlines for when I can’t think of punchlines” strips in book three.]
