The swan thing originated with a Sun article. Soe people were camping out in tents near London and there were a pile of swans' wings outside. They refused to come out of the tent to speak to the reporter but said they were Polish. If I remember, the article said there was a copy of the bible in Romanian on a table by the tent flap.
Lol. "Some people near London" - That seems reliable source.
On the other hand - I admire the professionalism of the said reporter. As a Polish, I am supposed to be a kind of expert on the swan-related matters, but honestly - I couldn't distinguish a swan's wing from any other white ones. The same with the Bible in Romanian. I couldn't say if that is Romanian or any other language.
I really love this story. :-)
Seriously though - I don't understand why this story was so shocking? As far as I am aware - there is strong taboo against eating the swans in Poland, but until recently the Swan-dish was a part of British cuisine. So what the fuzz?
