Why is it that on the night you really fancy a Chinese Take-away, they are closed?

And whilst on the subject of inponderables (or is it Murphy's Law):

• Why do the Level Crossing gates always close as Gorse Fox approaches, when in a hurry. But never when he's not?
• Why does the knuckle-dragging 20-stone mouth-breather sit next to Gorse Fox on the train (as she did this morning)?
• How does John Prescott hang onto his job? In any commercial enterprise his record of failures and disasters would consign him to unemployment.
• Why do the BBC still make Eastenders?
• Why is that on evening the Gorse Fox really fancies a hot curry, he has a long train or car journey the following morning?
