AMERICAN Idol has had its share of unforgettable contestants.

But for every Kelly Clarkson and Carrie Underwood, there are a slew of other names famous for less glamorous reasons.

These are the weirdest American Idol contestants - so far.

WILLIAM HUNG

Perhaps no former contestant is as well known as William Hung.

William skyrocketed to fame in 2004 after his entertaining audition of Ricky Martin's "She Bangs" on American Idol aired.

The Hong Kong native performed before the singing competition's original judges, Simon CowellPaula Abdul, Randy Jackson, and longtime host Ryan Seacrest.

Though his rendition did not earn him the Golden Ticket to Hollywood, he went on to become an entertainer and motivational speaker.

And most recently, he became engaged to his girlfriend Hannah.

LARRY PLATT

General Larry Platt was a true groundbreaker in season 9.

The 75-year-old auditioned in Atlanta, singing his own memorable song Pants on the Ground, which criticized young people who wear their pants lower than their waist.

Larry, who at the time was 62, was ineligible to continue due to being over the show's age limit of 28.

Although he was quickly dismissed, Pants on the Ground rose in popularity, receiving over 150,000 hits on iTunes and over 10million views on YouTube.

It peaked at No. 46 on the Billboard Hot 100, and Larry even performed it live at the 2010 Grammy Awards.

STEVEN TYLER

Years before he would take his place on the panel, Aerosmith legend Steven Tyler shocked Nicki Minaj, Mariah Carey, Keith Urban, and Randy Jackson in 2013 by performing in drag.

Steven put on a dress, blond wig, and bright red lipstick for his big break. But his famous face was instantly recognizable.

Going under the moniker Pepper LaBeija, the Dream On singer was dreaming if he thought he could pull a fast one on the judges.

Although he never actually sang anything, the rocker did manage to squeeze one of his fake breasts to make it honk.

He then threw it at Randy Jackson.

As the judges roared with laughter, Pepper ripped off his wig and mooned the judges.

MARY ROACH

Mary Roach was a contestant on season 4 of American Idol, singing I Feel the Earth Move by Carole King.

She failed to move the judges with her off-key voice and wild arm flailings.

"Honestly one of the worst I’ve ever heard in my life," Simon said to Mary’s surprise.

Simon then dared to question: "What made you audition for this competition?"

Mary replied: "All my friends told me that I was an awesome singer."

The audition took a further turn when she casually mentioned that she has a ton of different voices, to which Randy asking if they were all in her head.

The "voices" then went off on the judges, bashing them and their decisions.

“Not only can you not sing a note in tune, but you also have one of the weirdest voices I’ve ever heard in my life,” Simon concluded.

SARAH GOLDBERG

Sarah Goldberg sang Dreaming of You by Selena for her season 6 try out.

The 20-year-old strode into her audition decked out in a tiny red cowboy hat, which she immediately ditched.

Sarah was ditched almost as quickly after her off-key performance.

"I'm not a singer," she admitted to no one's surprise.

The judges then asked if she only auditioned for fame.

"Even though I can't sing, I could still be the next American Idol," she answered, before revealing her grand plan. "Because I've never sung before, and you can teach me."

"I could be the only American Idol who has never sang before. I'm unique!"

The judges weren't swayed, and Sarah was sent home.

STEVEN THOEN

Steven Thoen, who also goes by the nickname Red, admitted he rarely watched Idol.

"I'm not a big fan of the show," he openly confessed during his season 6 audition.

Steven sang Bohemian Rhapsody for the judges in a pitch so high, nearby dogs were in danger.

Simon called Steven's audition one of the weirdest he'd ever heard.

"It was like a one-year-old singing that song," the musical judge said.

All three judges voted no, eliminating Steven from the competition.

NICK ZITZMANN

Nick Zitzmann's season 6 dreams were popped after he garbled Unchained Melody.

The Utah native sang out of tune and tempo, giving him a ghost of a chance of advancing.

"What the bloody hell was that?" A shocked Simon asked.

Paula goaded the producer, sarcastically asking: "So, that would be a yes or a no, Simon?"

Simon shot back with another declaration that Nick was "one of the worst I've ever heard."

MARGIE MAYS

Margie Mays has been described as the most energetic audition ever.

She sang Shot by Lawrence for her audition in season 17.

The 25-year-old freaked out and nearly forgot who she was when she stood before the judges.

"This has been the coolest day of my life already, and I haven't even sung for you," she said at a rapid rate.

"I've never seen someone with so much energy," Luke Bryan said.

Katy Perry followed that up with a question: "How many cups of coffee did you drink today?"

Margie replied she had only had one.

"Don't ever have coffee again," Katy ordered.

Margie's performance perked the judges up as well, and she was awarded a ticket to Hollywood.
