Over the years, The X Factor has seen some truly shocking auditions. From out-of-tune singers to the down right bizarre, here are our five most memorable.
Ablisa
Attempting to come across as all sweetness and light, Abi and Lisa (collectively known as Ablisa) got off on the wrong foot by branding Louis Walsh 'old' and telling the audience to 'shut up' after they became impatient with the girls' inability to string a coherent sentence together. Things didn't improve for the duo when they decided to murder Shayne Ward's 'That's My Goal'. After receiving negative feedback from Natalie Imbruglia, who told them: "The singing was not great girls", Lisa retorted: "Who are you may I ask?" Clearly an Imbruglia fan, Abi then punched Lisa in the face, leaving the judges and audience in shock.

Ariel
Over-confident and seriously scary holistic vocal coach Ariel auditioned for the show in series five. Storming into the audition room, Ariel tore off her audition number and threw it at Dannii Minogue saying: "First of all let's sort this out, I'm not a number, I'm a human being." Things didn't get much better for the singer when she performed a self-penned song designed to show off her range of vocal abilities. Unimpressed, Simon Cowell told April that it had been a 'complete and utter nightmare'. After arguing with the panel, Ariel then started singing her goodbye. Sounding remarkably similar to the sounds that you would associate with an exorcism, Ariel sang: "I will say goodbye to you, but not before I have advised you, that you might want to shove a load of metal right up your a***." Charming.

Rachel
Self-assured Rachel auditioned for the show in series four with the belief that she would win the show. When asked by Sharon Osbourne how she would rate herself on a scale of one to ten, Rachel cockily replied: "Ten, whatever song you want me to sing, I'll do it," followed by the outlandish claim that she was 'better than Madonna'. After murdering her song, Rachel immediately turned to the panel saying: "That was good wasn't it, let's face it." When she received a resounding no, Rachel launched into a tirade of foul-mouthed abuse at the judges and was promptly escorted out of the building.Watch Rachel's delusional audition here
Shirlena
Possibly the most original interpretation of Duffy's 'Mercy' the world will ever see, Shirlena made a big impression on the judges during the seventh series of the show. Growling and shouting 'We need nercy, we do', the perplexed judges looked on as she began to gyrate her way through the song.Watch Shirlena's original performance of Mercy here
Goldie
Throwing up into a Morrisons carrier bag seconds before her audition began, 48-year-old Goldie somehow managed to surpass this first impression with a decidedly bizarre performance. Singing unknown song 'Copper Bell', Goldie seemed to have put her illness behind her. With her energetic performance, including wrapping her leg around Gary Barlow and ending by doing the splits, the judges were somehow impressed, putting her through to Boot Camp.
