Yoo Jae Suk has developed a new nickname.

Similarly to last week's episode, Ji Jin Hee,�Lee Chun Hee,�Joo Sang Hyuk, and�Kim Sung Soo starred�on this week's episode of Running Man that aired on January 15th. This week's objective was to win a bingo race.

With IU as a special guest, the teams could now split evenly into three groups. They arrived on the island and started the treasure hunt to look for pieces of paper with numbers written on them.

The island was so vast that finding the papers was like finding needles in a haystack. As the teams were out looking for the papers, Yoo Jae Suk's team and Ji Jin Hee's team bumped into one other.

Yoo Jae Suk sang and danced to Girl's Generation's 'Gee' at 'Ji' Jin Hee, jokingly making fun of his last name. Ji Jin Hee responded by saying, "How can we call him a mere grasshopper, when he is the nation's grasshopper!"

After Ji Jin Hee's response the other members also made fun of the "National Grasshopper" and instantaneously, Yoo Jae Suk new nickname was born.
