IGIRISU

I was eating breakfast - then for some reason, I had an epiphany, and came up with the LAMEST PUN EVER.

I'll explain, since it sucks so much...
As we know, in Japanese:
England = Igirisu
and
Risu = Squirrel

...
THUS, IgiRISU!!!! Or if you prefer Squirreland!!

AHAHAHAHAHAHAHAHAH

I'm sorry Arthur. I'm sorry Himaruya-sensei. I'm sorry, Great Britain...
