A man, his lodger, a two-seater sofa and a supermarket loyalty card conspire to cause misery.

Vince is promoted to swimming instructor and begins to teach a would-be glamour model, much to her husband's annoyance. Meanwhile, Errol decides it's time to redecorate the bathroom.

After discovering a new cut price supermarket, Vince becomes rather keen on its own brand energy drink Blue Rat - all the energy of a rat trapped in a can. Meanwhile Errol realises one of his life ambitions of working with fish.

Vincent falls in love with the woman upstairs, but can he pierce her icy heart?

After ejecting a troublesome child from the swimming pool where he works, Vince is targeted by the local gang, who will stop at nothing in their quest to destroy him. Well - almost nothing.

Vince is accused of a crime that could have him facing jail, but an archaic legal loophole means he might get off. Errol is suffering from a bout of vertigo.
