Song Ji Hyo and Kang Gary, who are affectionately called the 'Monday Couple' by fans who watch the hit SBS variety program "Running Man," discuss what they do when it's not Monday.

During the latest episode of "Running Man," a staff member acted as a department manager, and asked the cast members, who were named the Big Seven Company, what they did before they film during Mondays.

When Song Ji Hyo was asked what she does during the weekends, she honestly said, "I slept all weekend to prepare for Monday," pertaining to her blank and sleepy nature during the show; however, they didn't believe her.

Another cast member told her, "There was a rumor that you spend the weekends with Gary," to which Kang Gary retorted, "I didn't go with Ji Hyo, I went with another woman. We only meet each other during Mondays," making everyone on set laugh.
