Apparently 'illegal immigrants' on average eat four Weetabix before attempting to swim across the English Channel from France before an imaginary trespassing onto someone's property. It is also the breakfast of choice for all those 'illegal' food delivery drivers, they wash it down with tea grown in some unspecified African country (they don't drink 'native' English breakfast tea as they despise the English and our civilised way of life). This is what makes them so fast on their bikes, the motors they have are actually fake in an attempt to conceal how powerful they actually are, ready to overthrow us 'native' English people on a moments notice*
*Some of this may not be factually accurate.
