Eccentric rapper Psy revealed an interesting, albeit a little unusual dating habit through his guest appearance on MBC's 'Radio Star'. During the show, the singer confessed, "When I go out with a girl, I like to smell the crown of her head. ...A person's crown exhibits a smell unique only to that person." Candidly, he continued, "No one can mask that scent. No matter what hair products they use, their crown starts to smell. When a really clean-looking girl starts showing smells that are 'human', I feel a sort of sexiness." Psy then demonstrated how he would smell the crown of a girl's head using comedian Kim Gura as his model. Kim Gura did not look amused by the singer's actions and showed a look of disgust.
