Oh, Korean variety shows and their hidden camera pranks! On the latest episode of JTBC's 'Going to School', Kangnam and Kim Soo Ro decide to prank new member San E by pretending to fight. San E hilariously and very easily falls for it.

Kim Soo Ro first tries to prank Kangnam by asking where his 'disappeared' milk went. Kim Bum Soo was not so good at playing along, and Kangnam quickly figured out it was all fake.

Then Kim Soo Ro went for his next target: San E. Both Kim Soo Ro and Kangnam start arguing back and forth. Kangnam pretended to pack his things, saying he'll leave, making San E burst out his English from the tense environment. 

San E exclaims, "Yo, man. What are you doing, man?"

Kim Soo Ro then attempts to get at Kangnam and says, "I'm going to shave your head." Kangnam says, "Cut it then. Should I get you scissors?" Like a good mediator, San E tells Kangnam that it's wrong to keep arguing back even if Kim Soo Ro was the one who was wrong first.

San E eventually tells Kangnam in English, "You know that it's different here in Korea right? You have to respect elders. You know that, right? Just spend the night ,and it'll all be good." Meanwhile as San E tells him this, Kangnam leans forward to hide his laughter. Later o,n Kangnam says, "I'm sincerely sorry on the inside. San E is a really innocent hyung. I'm going to prank him again."
