Editing Mark Corrigan (section)

== Personality ==
Mark and Jeremy refer to themselves as "The El Dude Brothers," a nickname from their university days. Mark is generally sensible and careful but occasionally exhibits paranoia and impulsive behavior. His upbringing seems to have been somewhat unhappy, marked by a domineering father and parental infidelity. He attended Polefield School in Croydon, graduating in 1991, and holds a Business Studies degree from University of Dartmouth, where he met Jeremy. He earned 7 GCSEs and has a strong interest in history, particularly ancient history, which he initially wanted to study at university before his parents persuaded him to pursue Business Studies instead.

Mark is aware of Jeremy's lower intellectual capacity but still relies on him for social guidance, as he struggles with extreme social awkwardness. He often feels paranoid about how others view him and questions the normalcy of his own actions. Mark is notably Euro-skeptic and often has difficulty understanding modern societal norms, participating in activities that others seem to enjoy without fully engaging.

His relationship with [[Sophie Chapman|Sophie]] is a central theme in the first four series. After their failed wedding and breakup, he dates various women in Series 5, searching for "the one."

After leaving JLB, Mark works as a waiter at the Mexican restaurant Banditos, a bathroom equipment salesman at Bath, Bathrooms, and Fittings, and eventually returns to working as a loan manager at Met City Bank, where he is ultimately fired in the series finale.
