Lee Joon forgot the dance to an MBLAQ song.

On MBC's "Bilnd Test Show 180 Degrees," which aired yesterday, Lee Joon performed the dance to MBLAQ's song 'It's a War'.

Lee Joon, who confidently came out as the song came out, said "Oh, wait", and stood confused, admitting that he forgot the dance. The onlooking cast members asked, "How do you forget your own group's dance?", and Lee Joon explained, "I forgot because the music came on so suddenly."

Lee Joon then returned to the stage and naturally showed the dance to his song, showing off his charm as an idol.
