Choi Hyo Jung spoke about his days as a student when he was known as a tattletale.

On the latest 'Happy Together', the comedian confessed, "I was a tattletale when I was a student."

Choi Hyo Jung said that he will tell teachers about which students were smoking and which were ditching school. He went on to say, "I even got hit by a female student. I had a friend named Yoo Mi who [didn't like what I was doing], so in the middle of the gymnasium, she slapped me 17 times," causing everyone to laugh.

He then said, "But right after I got hit, I told on her to the P.E. teacher. For the next two weeks, Yoo Mi had to scrap gum off the ground and under the tables."
