Actress�Park Bo Young's head size�has become a hot topic.

On the October 29th broadcast of KBS2's 'Hello',�Son Dam Bi, Park Bo Young, and Yoo Young Yi appeared as guests and listened to the dilemmas of viewers.

Before getting into the viewers' issues, Kim Tae Kyoon stated, "Park Bo Young, how does it feel to have a small head?" He then said to himself, "It's a feeling that I will never be able to experience," which prompted�Jung Chan Woo to say, "It must feel nice to be able to wear a polo shirt."

Lee Young Ja then suggested that they compare the heads of Park Bo Young and the Cultwo members. Cultwo's Kim Tae Kyoon and Jung Chan Woo sat on either side of Park Bo Young, and the guests were astonished to see that the actress' head was only half the size of the two comedians.
