MBLAQ member Lee Joon's hidden gambling talent gained much attention online.

Today on MBC's "Idol Manager," MBLAQ members Seungho and Thunder celebrated their birthdays as Mir, G.O and Lee Joon surprised them with a party.

Before the show, the group split into two teams to find birthday gifts for the two members.

On the way, there was a stuffed animal game machine and Lee Joon suggested that they try to win the animal as a gift.

However, it did not seem like they would be winning the stuffed animal anytime soon. Lee Joon kept saying, "One more time! One more time please!"

Park Kyung Lim commented, "If you keep at it, it's going to be like the old days where people sold their houses and their land to win the lottery or gamble."
