Seems this doesn't work in English since the word "capital" (首都 usually translates to) has a broader meaning.

It was "what," not "where." More precisely, it could be the New York State Capitol in Albany.

So, in response to the question ニューヨークの首都は？ ("Where is the national capital of NY?"), answering オールバニ ("Albany") would be a 2 level deep joke. i discovered this.

However, if we take the term 首都 ("national capital") simply as the capital (which is impossible in jpn), the closest would be Albany for NY.

"Where is the national capital of Europe?" also works. That line appears in the anime of Baka to Test to Shoukanjuu, season 1, episode 7.

In Japanese popular culture, there's a joke: "Where is the national capital of New York?" It expresses that the person is ignorant and mistakenly believes that NY is a country.

I discovered that the national capital of New York State (ニューヨークの首都) is Albany (オールバニ or アルバニー).
