It must be Serbia then?
I vote for Serbia too lol. I just love the ring of it:
"Blame Serbia, blame Serbia,
With their 8 crappy borders in the middle of the Balkans.
Blame Serbia, blame Serbia..."
While on the South Park theme,
"Kazakhstan's a Bitch"
"What would Argentina do"
and the great Elvis favorite: "In the Gestapo" (yeah, I know it's not a country, but it works for me)
