Boy group iKON brought laughter to their fans with funny faces.

On Friday, the portal website Naver V App aired "SUMMER VACATION" with iKON.

On this day, iKON spent their summer vacation at the Jeju Island and went cart-riding. Members Bobby and B.I did live broadcasting of the cart racing of their other members.

"Reporting from Jeju Island. The weather is great with a blue sky," said Bobby.

But the two got distracted from broadcasting and started making funny faces at the camera- holding a competition about who can make an uglier face.

WINNER and iKON will be airing a total of five episodes of "SUMMER VACATION" beginning with the one aired this week.
