Recently on SBSTV's "Heroes", the cast experienced the life of a hotel worker, with�Seo In Young specifically being assigned the job of a hotel maid. The singer had to carry out a task of cleaning a bathroom toilet. Although she wasn't too happy and grumbled her way through the rather difficult task, she gave the toilet bowl a thorough cleaning. As Noh Hong Chul criticized her cleaning skills saying, "The hotel maids make it very clean", Seo In Young responded, "Be quiet," revealing her angry -yet adorable- side. Source: TV Daily via Nate
