I’m sure creme eggs used to be sold in boxes of six, so if you were a family of two, three or six, you needed to buy only one box for each member to have an equal number of eggs. A family of four, would have had to buy two boxes and a family of five, six boxes. Under the new scheme of five eggs per box, a family of five would need one box and the other permutations (up to six) would need a box each to make it fair. So in a partnership, who gets the extra egg if you’ve only bought one box? The wrong answer could lead to a pribble (‘A petty or pointless dispute, a squabble; trivial or nonsensical speech or writing; squabbling, quarrelling; idle chit-chat. Only in collocation pribble and prabble’, OED). BTW, the right answer is “me”.
