Yoo Jae Suk became a drowned ghost thanks to clueless Jung Jun Ha on the recent episode of MBC's 'Infinity Challenge.'

The latest broadcast aired the second episode of summer camp special where the cast enjoyed various games. During a particular game, if a member said or did a forbidden word or action, his partner would fall into the pool. 

Yoo Jae Suk and Jung Jun Ha were partnered up and Jung Jun Ha was forbidden to say "I am" or look at his partner. Totally oblivious to the clues, Jung Jun Ha kept on saying "I am" in every sentence, causing Yoo Jae Suk to keep flying into the pool. Then, feeling sorry for his partner, Jung Jun Ha kept looking at him so that Yoo Jae Suk could't enjoy one minute of dryness. 

The cast all clutched their stomachs as HaHa finally shouted at him, "It's 'I am' 'I am' you stupid!"
