The ever playful jokester Yoo Hee Yeol livened things up as usual on his show, 'Yoo Hee Yeol's Sketchbook,' on December 12 by teasing one of his guests, INFINITE's Sunggyu, who appeared with Yoon Sang as the two recently released a collaboration.  In addition, a sub-unit called INFINITE F with Sungyeol, Sungjong, and L, recently debuted, which was the basis of Yoo Hee Yeol's joke.

He lightheartedly joked, "I heard the F in INFINITE F stands for 'face,' so you were eliminated based on your face."

Sunggyu wittily joked back, "Since it's a group I'm not in, I don't really want to mention them here," making everybody explode into laughter.  He continued, "Face... I didn't think I was left out because of my face, but..." and Yoo Hee Yeol made things right by emphasizing how Sunggyu stood out as the main vocal all the time.  The idol also updated on his life, revealing he was taking a nice break at the moment.
