Defconn congratulated Ha Ha on his recent comeback by tweeting, "Proof that I was watching Ha Ha's comeback "Rosa" on Music Core! I saw it! It was really good!", and uploaded a hilarious photo of himself dancing in front of his TV. The phrase "I saw it" was started by Jung Hyung Don on 'Infinite Challenge' and it has now become the popular phrase which makes Defconn's tweet all the more hilarious. Netizens responded with comments such as, "Defconn is a true brother", "Infinite Challenge bonds men into brothers", and "His comment cracked me up". Ha Ha recently made his comeback debut on the 17th with his new reggae track, "Rosa". Source & Image : StarToday via Naver
