An interesting video parodying the SBS program 'Pair' has been revealed online, allowing people to vote for 2011's best duet couple. A video titled '2011's Best Musical Duet' surfaced on various online portal sites.  It starts with a female voice narrating the beginning, just like in the actual SBS series. The video introduces singing duos that have released a single together in 2011, with the exception of sub-unit members from the same idol group.  The candidates for the duet couples were: SECRET's Song Ji Eun and Bang Yong Guk for "Going Crazy". Wheesung and B2ST's Yong Jun Hyung for "Heartbreaking Story". IU and figure-skater Kim Yuna for "Ice Flower". Bang Yong Guk and B2ST's Yang Yoseob for "I Remember". Kim Bum Soo and Park Jung Hyun for "Person, Love" Veteran singer Kim Wan Sun and B2ST's Yong Jun Hyung for "Be Quiet". The video is especially hilarious as it features same-gender 'couples' that have yet to be paired on the SBS series, while singer Kim Bum Soo is introduced as a handsome 'Visual' singer, and Kim Wan Sun is a whole 20 years older than her 'pair', B2ST's Yong Jun Hyung. Netizens showed their individual support for their favorite singers and showed interest by making comments, "This is pretty cool", and "Bang Yong Guk's image in both of his nominated songs are so different". So, who's do YOU think was 2011's 'Best Duet' couple?
