Hellen "Greg" Gregson, best known as Mr G, is a fictional character portrayed by Chris Lilley in the Australian mockumentary series Summer Heights High. The character also appeared in the sketch comedy series Big Bite. Storylines Sometime prior to 1998, Mr G graduated from the Teachers' College of Macquarie University in Sydney, where he completed a Bachelor of Arts, majoring in the performing arts (music, drama and dance), and a Diploma of Education. Mr G became a drama teacher at Summer Heights High in 1998, 9 years prior to 2007. He first appears in Big Bite set in 2003 as a Drama Teacher, in which Mr G hosts the annual Rock Eisteddfod Challenge; he calls the show 'Vietwow' which is based around Australia's involvement in The Vietnam War and brings home an award for the performance. Later on Mr G is asked to host a performance for the opening of the new school pool, which is being opened by Olympic swimmer Ian Thorpe. After being denied several ideas he settles on a performance on the Sinking of the Titanic. Some years later in 2007 on Summer Heights High, Mr G is supporting Head of Drama Mrs Meredith Cotton with the upcoming school production of Anything Goes. He then brags about his life story in performing arts and discusses a typical drama class, where he incorporates his unique teaching style. He sees his role at the school to teach drama and dance to change lives, inspire students, and to encourage the students to dare to dream. Along with his loyal sidekick, science teacher, Mr Rodney Parsons, Mr G criticises and is frustrated by his superior Mrs Meredith Cotton, as well as complaining about the lack of funding and support given by the school's principal. The Head of Drama, Mrs Meredith Cotton, had to go to New Zealand due to her mother suddenly falling very ill, and therefore Mr G was promoted to Acting Head of Drama, renaming his title as "Director of Performing Arts". Thrilled with the temporary promotion, he makes a few changes such as clearing-out Ms Cotton's desk and moving himself in, and walking around the school to pass on the news to students of his new role. He also gets support staff to do work for him, complains about noise from the gym, and requests teachers "under the umbrella of Performing Arts" to fill-in classes and duties he
