Q - How many David Camerons does it take to change a lightbulb? A - Well, first of all he has to turn off the electricity by pressing the switch. You'd think this first step would be easy, but on the way to the switch he meets Lib Dems who try to convince him not to cut off the power so quickly, an angry rabble of Trade Unionists who threaten to strike if he goes near the light switch, and the BBC who plaster his face with unbiased propaganda about the 'correct' way to respond to light switches. When he finally battles his way through to the light switch he meets an EU representative who tells him he can't turn it off because under EU legislation he must install two new light switches while also paying for Greece's faulty light switch. In the end Dave decides to go home because he realises it is impossible to turn off the light switch due to the way Labour installed the wiring. Put simply, the light switch will stay on forever, blazing up a huge bill, until it explodes. Then we'll all be in the dark.
