Sunny talks about her growth spurt and dishes on which Girls' Generation members wear insoles

On August 28, Sunny appeared on KBS 2TV's 'Happy Together 3' and had fun talking about her height. 

She explained that she started growing taller during her school days, which made her happy.  She continued, "However, one day, I hurt my knee.  I went to the hospital where they told me there was a small infection, so I needed to take medicine.  But then the doctor said suddenly, 'But it looks like the growth plate shut off?'  For a young girl, that was like a bolt out of the blue."

She revealed she was 158 cm (~ 5' 2") tall.  She said, "There are some members who put in insoles.  Besides me, there are Taeyeon, Hyoyeon, Jessica, and Tiffany.  If the tall members use insoles, the average members use them, too.  In that case, I put in about three insoles," making everyone laugh. When they measured her, Sunny was exactly 158 cm like she said she was. They also measured her face which came in at 16 cm (6.3 inches).

Sunny also revealed her method for looking taller than she really was: "I wear short bottoms and stick out my butt, so that my legs look long."
