During the 'Real Men' special of 'Quiz to Change the World', Tony An shared, "During the first initiation ceremony for the military promotions department, I opened up about my depression. Psy, who was a corporal at the time, said to me, 'An Seung Ho, during the time that you are here, we will make you happy. By the time I leave, your depression will be healed and gone.'"

"I asked him how I could become happy when I'm in the army, there are only guys and indecent jokes at night. But Psy would always say to the new recruits, 'I will do at least one obscene thing and make you laugh in order to go to sleep.'" 

"Even if it wasn't always an indecent joke, he encouraged us to laugh before going to sleep, so I would always laugh before going to sleep."
