Why are there always these bags of rubbish lying around London?
Because we got rid of all of the rubbish bins.
Why did you get rid of all the rubbish bins?
Because the IRA used to hide bombs in them.
Why don’t they put the bins back now the IRA have stopped bombing things?
Because now the
Arabs fundamentalist Islamic terrorists might hide bombs in the bins.
Why won’t the terrorists just hide bombs in the thousands of bags of rubbish lying around on the streets?
