On July 16th aired episode of SBS 'Running Man', Lee Kwang-soo and Jeon So-min showed their funny talents that made people to burst into laughter.
In order to go on a trip to the '1% vacation spot', each Running Man members had to win various races.
During the 'meal mission', Lee Kwang-soo suddenly appeared with funny looks―so called 'Young Goo's not here' looks, and unexpected people began to burst out laughing.
'Young Goo's not here' look came from a famous Korean comedian named Shim Hyung-rae, who developed a dumb character named 'Young Goo'.
Like Kwang-soo, comedian Shim Hyung-rae would have black teeth and verbally say "Young Goo's not here" to show his mindlessness.
