Jeff explains to the guys about 'The Giggle Loop': the danger that the more you try to suppress laughter in important silences, the harder you want to laugh. Jane's aunt has died, and she wants Steve to come to the funeral, pretending to be her boyfriend still. Susan invites herself, and so Patrick must come as her 'boyfriend', and all six end up going.
On average, men and women think about sex every six seconds. Shorten that to every second, and you've got Coupling.
This series centers around Susan and Steve (who are a couple), and Sally and Patrick join the gang as friends of Susan (and then Steve), while Steve pulls in his best friend Jeff and his crazy ex Jane.
