Sex, Death and Nudity

Size Matters is the second episode of the first season of Coupling. It aired on the 19 of May, 2000.


After an out of control pause during a phone call, Susan invites Steve to dinner, offering to cook. While discussing foreplay, Jeff warns Steve of the perils of falling into the Sock Gap and also to look out for Susan’s remote controls. Sally tries to overcome her aversion to Patrick’s political views when informed of his main attraction and Jeff freaks out when Sally, Steve and Jane give him an unusual task.

Susan and Steve prepare to go on their first date (or at least, their first date without their friends gatecrashing.) Susan suggests that she’ll cook, sparking debate as to whether that means she’s inviting Steve to have sex too.

Susan tells Sally - and Steve - that Patrick is particularly well-endowed.

Sally is undecided about Patrick

This leaves Sally with a tricky dilemma: she’s always sworn never to have sex with a Tory, but Patrick is a very big boy... Meanwhile, Steve is increasingly intimidated by Patrick’s huge reputation, until Susan finally puts him at ease.

Embarrassing Moments[]

Steve phones Susan for the first time, but can’t think of anything to say. The pause is so long it takes on a horrible life of its own - "like the Blob", in Jeff’s words.
