I know this is old but I just saw it now.

This is a still from barefoot friends.

The cast and the guest were playing a quiz so they could eat delicious food

So the question was like

PD-"Colour food leader of healthy curry is famous in which country?"[I have no idea what it means...not a cook]

Hodong- "India"

Then the PD asks them what's the capital of India

SO Apink's Eunji's answer was so unexpected

She said the capital is Taj Mahal [Rofl] like seriously 'taj mahal'

But it does not end here

Hyunjoong was also a guest on the episode and he said that Taj Mahal is a religion. (this was worse than eunji)

Then Hyunjoong says the answer is Jakarta. At this Kang Hodong explains him that he goes to Jakarta in Indonesia and not India.

Later one of the mc confuses India as Indonesia's capital. He then asks is India another country.

Kang Hodong was laughing like mad person at this point. He asks eunji whether India and Indonesia are different countries or no.

Eunji is confused and says : "Isn't it the same?"

Hodong gets frustrated and says : "If we don't know even this then we should leave"

Later Kang hodong answers it correctly 

"NEW DELHI"

At this eunji gives another blow saying "Is that even a city? Sounds like a restaurant"

I guess Eunji and the cast of the show (Except Kang hodong-shi) needs to brush up thier general knowledge. Even if they don't know the capital they should atleast know that Taj Mahal is one of the 7 wonders of the world.
