B1A4 sat down for an interview on the August 8 installment of 'Yoo Hee Yeol's Sketchbook' and talked about maturing as artists, mentioning that this was hard to do at the moment because of their young fans.

They were asked whether they had any ambitious to do a group dance that gave off a manly and sexy vibe.  The boys replied, "It will probably come out naturally as time passes.  We'd probably do it when we're older."

They explained, "We are even refraining from curses in our lyrics for our fans in their teens.  The worst curse in our lyrics is, 'Idiot.'  A song in our album called 'A Cup of Water' was originally 'A Cup of Alcohol.'"

They also revealed that their lyrics were becoming better in quality from the past, and had fun looking through Baro's lyric notebook, which you can see in the video above.

As for their growth as artists, maknae Gongchan even said, "I want to film a bed scene in the future."  The other members said that Gongchan had a very firm butt.
