Jung Joon Young went into a mental breakdown when he discovered a miniature doppelganger of himself on '1 Night 2 Days'!

The cast members were given the mission to find lookalikes of each other on the latest episode. Defconn and Kim Joo Hyuk brought back a teenager who looked like a carbon copy of Jung Joon Young when he was younger, to the surprise of the celebrity!

That wasn't all, however, as the doppelganger perfectly emulated his voice and speaking style, sending Jung Joon Young into a panic. When Defconn urged the kid to introduce himself, he said, "I'm Jung Joon Young. Who are you?", sending everyone into fits of laughter!
