Carrots

Why are they the only thing that seems to have remained stupidly cheap?  Can still buy a huge bag for about 60p.  Let them eat carrots.

Where all other rational possibilities have been excluded one must draw the inevitable conclusion that carrot farms are being subsidised by the League of Red-headed Gentlemen. 

I've got some unplanned spuds growing in my composter. Do you reckon theyll be ok? 

Yes.  The lesson is, don't put the "eyes" in your composter, they will grow.
