The challenge was to read a set of 36 words in their correct colors as fast as possible. Though the other Block B members stumbled over the words, hesitated, and read the words as they were, Zico calmly went through the entire set in 25 seconds. Jun Hyun Moo, with his pride as an announcer on the line, tried to beat Zico...but failed miserably. 

Do you think you can beat Zico's time on this brain teaser?
