It is a well known, and proven, medical fact, that itchy fingers are caused by a severe depletion of the correct intake of beer in the human diet. The reccomendations, generally, are that you visit the pub more often or, if severe snow prevents this, have an order delivered by Tesco's, in order to imbibe at least half a gallon. However, it has also been proven that excess intake of the said liquid, can result in the dubious quality of any modelling work undertaken directly after imbibing the said liquids. But, who gives a d*mn when you've got that floatly warm feeling?!!
