Kang Ho Dong seemed to have finally overcome his slump in viewer ratings with last week's episode of MBC's 'Knee Drop Guru' topping its time slot, but that quickly went downhill this week as the show was forced to air a re-run due to controversy surrounding their guest, Kim Mi Kyung.

According to AGB Nielsen Media Research, the March 21st broadcast of 'Knee Drop Guru' achieved a 2.8% viewer rating which was a steep 5.4% decrease from its previous viewer rating of 8.2%. The show aired a re-run for this week as star-instructor Kim Mi Kyung is currently under the suspicion of plagiarizing a paper.

Meanwhile, KBS 2TV's 'Happy Together 3' claimed first�with 8.2% viewer rating and 'Star Couple Show' achieved a 7.2% viewer rating.
