F.T Island's Hongki will engage in some 19+ rated conversation on this week's 'Witch Hunt'! As a preview, it was revealed that one of the topics he touched upon was receiving female underwear while performing on the stage.

He said, "During the world tour, women's underwear was flying onto the stage, so I was really surprised.  I was singing on stage when over 20 women's underwear flew onto stage."

Shin Dong Yup recalled a similar event when the nation's female students did the same during Cliff Richard's concert in Korea back in the 1960's.  He said, "When I heard about the news from that concert, I thought to myself, 'When will our nation's singers be treated so fervently overseas by fans throwing underwear from the seats?'" making everyone laugh.  

This isn't the only time this happened, either, as previously, 'Music Bank in Mexico' also had to halt filming at one point because of fans throwing underwear at EXO and B.A.P!

The episode airs tomorrow if you want to hear more interesting things from Hongki!
