Time for some 19+ jokes on KBS 2TV's 'Yoo Hee Yeol's Sketchbook'!

On October 9, Lil Boi was asked why he chose his name.  He explained, "It's short for 'Little Boy.'  In the end, it's because it's small...  I was unable to be Choiza," making everybody crack up.

Most people are aware that Choiza stands for "greatest penis" because he allegedly has a big one, so Lil Boi dissed himself by explaining his name meant pretty much the opposite.

On the other hand, Basick was also there that day and he said that he's never done music full-time.  He said, "I did music while I went to school.  I got a lot of interest during my breaks.  I went to school abroad, but seeing as how I was far from public eye, they immediately forgot about me."  Meanwhile, he had been active as a company employee, stating, "I worked for about two years at a sports fashion brand.  The model then was Son Yeon Jae."
