Ok, so here is the croissant that started all this mess:
When asked about what kind of animal might it be, the woman said: "It's this, oh, what is it called... A lagun!"
The devil works fast, but The Krakow Animal Welfare Society works faster:
They already made a merchandise with an illustration of the lagun - they posted information about it on Facebook on Tuesday evening and by the Wednesday morning everything was already sold out.
My university professors are so delighted about this story that they are writing tons and tons of limericks, moskaliks and lepiejs (those two last genres are very popular, ridiculous and humorous types of short poems, in last decades popularized by Wisława Szymborska) and posting them on official Facebook pages of our university departments, and I am dying of laughter.
