The credit crunch has hit the household of Dr Joseph McCrumble. He clings to the memories of his time as a celebrity scientist (with expertise in the exciting field of parasitology), but now lives in a partly-converted, wooden barn with his family (wife Dolores, twin boys X and Y and a two year old toddler, No. 3) as well as Ravel, his faithful research assistant. He needs to keep going for the sake of reviving his career. His family just wants a home built of brick and a 24/7 electrical supply.
