Seventy out of 4,500 prisoners at Bangkok Remand Prison put on a show Tuesday for the media and corrections department executives after competing in a "Gangnam Style" dance contest last week.
Officials said the program was to relieve inmates' stress and help them keep fit.
Psy's "Gangnam Style" this month became the most watched video ever on YouTube. It has spawned hundreds of parodies and tribute videos, including a popular one earlier this year by members of the Thai navy.
Psy will perform in Thailand on Wednesday night — his first show in Asia outside of South Korea.
