During the March 18 episode of Mnet's "Beatles Code 3D" Shindong talked about his other Super Junior members while Girls' Generation guest starred on the show.
Shin Dong Yup asked, "[In Super Junior], who is the most charismatic these days?"
After giving it some thought, Shindong admitted, "Eunhyuk is the ugliest member as always. During our training period, Eunhyuk would wear a shirt with Batman on it for 364 days in a year!"
He also revealed, "Leeteuk always wore cargo pants during our training period, and 10 of them would wear beanies. It made me think that perhaps a Batman t-shirt, cargo pants, and a beanie would signify that you were an SM trainee."
