I was just watching Boom Boom Ba today, and to my surprise F.T. Island appeared! :DD I’ve seen a link to this video of the boys playing with Harlem Yu previously, but it didn’t click that they had actually appeared on the game show I was watching ^^.
This part is where the boys are versing the HK team in poking the most number of fish balls. Hongki did quite a good job XD;;;.
