'Superstar K' has been the birthplace of many famous singers. From Seo In Guk, Huh Gak, and Busker Busker to Ulala Session and more, 'Superstar K' has been annually showcasing superstars who have had us in awe of their vocal talents. And then there were those who had us in awe… for other reasons.

This 'Strong Baby' got some 'Sexy Back'

First up, we have contestant Lee Joon Ho who brings "Sexy Back" (0:12) as he does a little dance intro complete with fist-pumps and body waves for the judges. Check out that seductive gaze. Whew! 

Unfortunately for this contestant, after jamming it out to the Timberlake tune as well as to Seungri's "Strong Baby", he is promptly dismissed when he shouts, "GOODBYE MY PRINCESS." Judges be like, "Yes, goodbye."

The 'Loner's that want you to 'Come Back Again'

Next up is Kim Tae Min and Jang Hyun Gyu, two glasses-wearing, gawky, teenage boys who seem to have two very different problems. While the first has trouble singing CNBLUE's "I'm a Loner" without sounding like an emotionless robot, the second is way too into the Vibe feels. Seriously, check out that vibrato.

Gaga Legs

This fireball of energy, Na Gyung Ho, brought a smile to TV viewers' faces for his bright and cheerful persona. Although he seems to offend the judges for his lack of proper footwear, he soon has everyone laughing with his fancy footwork to Lady Gaga's "Born this Way" (1:51). The judges go gaga for his legs, but not so much for his singing. Oh well, good effort.

Michael Jackson Chipmunk Version

Starting at 0:46, Hwang Dong Min decides to impersonate his favorite singer Michael Jackson for his audition. He definitely got the, "Ows!" down, but as for the rest? Erm. Maybe. If Jackson was a chipmunk.

Lower Your 'Expectations'

Speaking of hardcore fans, check out Yoo Jae Pil going wild for his cover of Girl's Day (at 0:39). As he shouts the lyrics and the, "Oooh, oooh, ooohs," he has the judges laughing at his stiff yet enthusiastic suspender-work and hip rolls. 

Ghost Whisperer

Go Joon Gyu's performance gave his listeners chills as he wails like a banshee for his audition (1:13). His performance certainly leaves the judges speechless to say the least. 

Someone's Got the Case of the Hiccups

Another giggle-worthy audition, Kim Min Soo has his judges desperately attempting to stifle their laughter with his hiccup-like singing.

"No, no, no, NOOOOOOOO!"

Make sure to watch Hong Jung Hwa's audition until the end when he unleashes his full vocal power and attempts with all his might to hit the high notes. Because THE LOUDER YOU SING THE MORE LIKELY YOU'LL REACH THE HIGH NOTES. RIGHT?

Hip Hop Master

Jang Mun Bok is on a mission to revolutionize the hip hop genre as he states in his interview, "In my opinion, Korean hip-hop is a bit lacking, as if it's unable to find its direction." He adds, "I'm here on 'Superstar K' to show my talent and so that I can help hip hop in Korea progress," before proceeding to rap (0:27) in a strange Crazy Frog fashion. Gollum, is that you?

The Macho-Man that 'Twinkle's

When he's not failing to do push-ups, clumsily high-kicking stuff over, or randomly speaking Russian, macho-man Park Sang Bo sings in a strained style as he squeezes out MC THE MAX's "Don't Be Happy" and thrusts to TaeTiSeo's "Twinkle," starting at the 2:46 mark. How can a person sing so badly? Well according to Park, the cheese in his sandwich he was eating prior to the audition was rotten, so he supposes that could be the reason.
