There's only one capital in Asia which I always forget. Of course this was the tenth country in my first try. :| Well, at least maybe now I'll finally learn it.
The capital of Bahrain always makes me think of Sesame Street and those 2 Swedish muppet girls with the psych ward-escapee-looking muppet singing "Manamana".
Could you give a little more time? It's hard to type all of the capitals in the time given, especially if you misspelling things (which I do often) or if the capital names are longer
edit: now i got it with 31 seconds left
