Editing Mark Corrigan (section)

==== Friends ====
Mark lives with his best friend Jeremy, and together they call themselves the "El Dude Brothers," a name dating back to their university days. This nickname is now typically invoked when one of them seeks the other's support, often against better judgment.

In the second series, Mark briefly befriends a colleague named Daryl, who turns out to be a racist. Mark claims Daryl is the first friend he made since Nick Bickford in 1996. Around this time, he and Jeremy were also friends with Pej.

Mark's boss at JLB Credit is [[Alan Johnson]], a charismatic yet domineering figure who seems to view Mark as a protégé. Sophie Chapman, whom Mark met at JLB Credit, transitions from being the object of his neurotic affections to his brief, reluctant wife. After a long falling out, they become friends and co-parents to their son, Ian. Mark also befriends [[Dobby (Peep Show)|Dobby]] and [[Gerrard Matthew|Gerrard]], forming a love triangle. He has a relationship with Dobby, but they split when she gets a job in New York.

Mark is very much a social reject; he is paranoid about nearly everything, overthinks situations (usually to the worst conclusion), and endlessly worries about wanting to seem normal—a goal he never quite achieves. His constant anxiety about this suggests he has accepted that he is not normal. Throughout the first two series, he obsesses over Sophie, and in the third and fourth series, he worries about their deteriorating relationship. Much of the fifth series is spent fretting over the stigma of being a 'jilter.'
