Why does the EU want more money when 90% of the EU budget is 'materially affected by irregularities?

the department of useless expenditure and straight bananas (the eu) needs money to make sure polish farmers have enough money to grow square turnips using genetically modified compounds to give a high yield per metre sq. were just a prop for eastern europe and if the eu can think of stupid ways of screwing more money from the west theyll do it.
