Constantly mocking their sister's employment at a local massage parlour, they spend most of their time joking around, taking drugs and stealing cars.

Their father, "Fatty" Lewis, falls from a ladder while doing roofing work for Bryn Cartwright, a wealthy, prominent local businessman and small-time gangster.

The twins take this personally and seek revenge by gatecrashing and ruining a local karaoke competition in which Bryn's daughter, beautiful Bonny is singing, by appearing from back stage and urinating on her during the performance in the Barons nightclub in Swansea.

Terry meanwhile, much to Greyo's distress, accuses Fatty's co-workers Dai and Chip of destroying the caravan by placing items from the scene of the crime in their builder's van.

When his wife Lucy arrives later that evening, she attempts to use the electric gate remote from outside while returning home, causing the garage door to lift, hanging Bryn.

On looking under the door and discovering the hanging, Lucy hysterically runs through the house and finds their daughter floating on a lilo in their indoor swimming pool listening to music through headphones, blissfully unaware of what has gone on.

The coffin floats for a while before the twins make a bet on how long it would stay afloat, seemingly brushing aside the emotion of their father's funeral at sea.
