There was a "guide to the 10 best euromyths" article on the BBC news website during the referendum campaign, according to which the EU have not only banned bent bananas they've also banned straight ones, and stopped British barmaids from showing their cleavage. All the stories are, of course, 100% ********.
The article quoted the actual EU regulations about fruit, which must be "free from disease and malformation", i.e. healthy. Obviously two scumbag tabloid journalists read it, and thought "how can I wilfully mispresent this in order to make is seem unreasonable?". One decided to pretend that bent bananas were malformed and the other that straight ones were, which is why we got two versions of this particular bit of nonsense.
