유재석
"Alcohol CEO" is also his nickname on this programme, a nickname he gained since he operates a Karaoke-pub in Gangnam-gu, Seoul called "Mong" (몽, 夢, means "Dream" in Korean). This, combined with the previously mentioned nickname Daegari, led to Yoo Jae-suk nicknaming him "Chivas Daegal" (a reference to Chivas Regal).
