During a recent broadcast of 'Superman is Back', Sam Hammington and his two sons William and Bentley visited Yoo Byung Jae's home.
The moments which caught netizens' attention during the Hammington family's time with Yoo Byung Jae was when William discovered some "dirt" on Yoo Byung Jae's face. The incident occurred as William took interest in a model figure of Yoo Byung Jae, comparing the model figure to the actual figure. After observing Yoo Byung Jae's face pensively for a moment, William said, "dirty."
The baby then took out a wet wipe to "clean" the dirt from Yoo Byung Jae's face... specifically, right above his lips, but for some reason, the dirt wouldn't come off of Yoo Byung Jae's face no matter how many times William tried.
Netizens commented, "William's face is so precious like his, why isn't it coming off o_o expression", "dirty kekekeke", "Poor Yoo Byung Jae-nim kekekeke. That's hurtful no matter how you put it", "One time my niece saw my brother's mustache and said there was a bug on him kekekeke. This makes me think of that", "That baby is seriously the cutest", etc!
