Shortly after, Jez claims to Toni that he has a terminal illness in order to receive sexual favours from her.
Peep Show is a British sitcom starring David Mitchell and Robert Webb.
The television programme is written by Jesse Armstrong and Sam Bain, with additional material by Mitchell and Webb, among others.
In the first series, Mark and Jez start out with similar aims of bedding their next-door neighbour Toni (Elizabeth Marmur), which Jeremy does - whilst she is separating from her husband, Tony.
Mark is obsessed with his workmate Sophie (Olivia Colman), who is more interested in their manly colleague Jeff.
Jez remembers having oral sex with Super Hans (Matt King) during a drug binge.
Sophie beats Mark to a promotion, so Mark and Jez desperately team up to prank call Sophie.
Meanwhile, Jeremy's efforts to get back together with Suze are hindered somewhat by Super Hans' attempts to go cold turkey.
During series 4, Mark and Sophie visit Sophie's parents after their engagement, and Jeremy has sex with Sophie's mother.
However, realising he was trying to get out of marrying her by hiding, she runs out on him after the ceremony, planning to seek a divorce or annulment because Mark is "horrible".
