Maths. That most hated of subjects for millions of schoolchildren every year. It's truly evil. And last night, it proved that its terrifying evil grip extends beyond the classroom and into reality TV, as Lord Sugar found himself having to fire four people at once because somebody somewhere had forgotten to match the number of candidates to the number of weeks they're on air.
You?d think that one of Lord Sugar?s minions can count, wouldn't you? But it seems that millions of pounds can't buy you competent staff or stop simple maths from cocking up your reality TV show.
And so Lord Sugar found himself with six children, and only two spaces in next week?s final. His solution to this problem? Popcorn.
