Read in the Guardian at the weekend that describing something good in parts as a curate's egg is quite wrong. Apparently the original 1895 Punch cartoon had the Bishop saying, 'Mr Jones, your egg is rotten.' The curate replied that on the contrary parts of it were quite good. The joke is that an egg can't be part rotten, so a curate's egg should not be something good in parts but something ruined by parts of it being bad. Now how many curate's eggs can we think of?
