It must not be easy being the youngest member of a popular idol group because Infinite’s Sung Jong recently revealed he keeps a special sandbag close for those moments when his anger gets the best of him.

The Infinite members took over Mnet’s open studio as the featured guests on entertainment news program Wide Entertainment News, where member Sung Jong revealed he takes his anger out on a big teddy bear he keeps on his bed at home.

When asked why he needs a sandbag at all, the other members burst into laughter when Sung Jong answered, “Don’t we all know why? From the stress I receive from the hyungs [older brothers]…I think that’s why I keep going to the teddy bear.”

The best part of the show, however, was when the MCs gifted Sung Jong with an actual sandbag and matching boxing gloves.

In his hilarious thank you speech, Sung Jong said, “Thank you for the sandbag. From now on I won’t hit the teddy bear and take care of things with the sandbag,”

The other members better watch their backs!
