I couldn't not watch this show because it was gaining so much popularity and still going. At first, I was a little upset for the fact that the show is full of men but I gathered later that it was for the best because this show is pretty intense of making jokes out of hurtful topics; crimes that was committed by the members.
To sums it, A Hyung I Know is like SNL in high school setting. All the students are trouble makers. And the celebrity guests supposed to play along with the setting as troublemakers who transferred into that school. There are quizzes on the celebrity guests, the sport games and the impromptu drama.
There are boring episodes but most of them are fun. I personally like the one where Red Velvet makes an appearance and playing the teenage daughters.
