During their guest appearance on a recent broadcast of 'Cultwo Show,' the�GOT7 members aired out some dirty laundry about each other, but mostly on�Mark.�

All throughout the show, Mark had to make continuous trips to the men's room as he wasn't feeling all too well. For some innocent fun, MC Jung Chan Woo recommended that they gossip a bit about Mark while he wasn't around.�

When the MC's asked about Mark's shortcomings, JB replied, "It's not a shortcoming, but [Mark] doesn't talk much." Jackson chimed in, "I was his roommate for three years but it felt like I spent that time alone," and joked, "It almost feels like he's not there. It was like he was a wall."�
