An old video of two Korean stars, Eugene Kim and Lee Hyori, arm wrestling on a variety show (presumably Happy Together) hosted by Yoo Jae-seok.
Eugene was a member of S.E.S, while Hyori member of Fin.K.L. The two girl groups were hugely popular before being unofficially disbanded in 2002. Hyori went on to become a successful solo singer, while Eugene is making her mark as an actress.
