why do these appear on friday nights?
it's funny because it's completely true:

We need to get to the people who only hear the rumours. Bottom feeders who get their views via the quotes from the models in the Daily Star. Van drivers who guard their vast ignorance with concealed Stanley knives. Businessmen who like to expose their self-aggrandising cynicism to schoolgirls on the Thameslink. These dumb motherfuckers are the battlefield. Shitheels. Dunderheads. People who when you talk to them it's like shouting through six pieces of double glazing. Potheads, cider drinkers, kids who don't know who Thatcher was and think the NHS grew on a big fucking NHS tree. Wankers.
