Лизиантус

Another group of school children was leaving the "ancient greek scuplture" hall, no one with a straight face (which was rather normal), some on all fours (which, probably, wasn't). 
-What makes 'em...like this, if I may ask? - the young caretaker has just finished doing up his jakcet and was now coming towards the chair, which was the repository of his elderly colleague, with an air of dignity and bergamot oil.
- Ah, here you are, lad! - the old man put his glasses on and took a better look. - You'll come to know it and ignore it, trust me on this.
He yawned, covering his mouth with his hand, and continued.
 - It was all those years ago... An archaeological expedition appeared to have gone terribly wrong from some point: someone has screwed up the maps, they've run out of everything but salt and vinegar, and finally have found themselves on a timsy little island, so small and god-forlorn that half of the greek have forgotten about it and the other half wouldn't remember the name...
Still, the men persevered... - the caretaker looked dreamy for a while and chuckled to his own thoughts. - 
That's where this...thing was discovered. Actually, it is a statue - which wouldn't normally strike one as something extraordianry - but this one's lethally wounded a man who's discovered it, and it was nothing short of a miracle that's saved his assistant from hilarious asphyxation...
Well, eventually they've found a way to deliver it here and be reproduced in a not-instantly-fatal manner. Still, whenever a school child sees one, he just can't help it. - From here new in-takes of breath could be heard, followed but silent seconds of extreme contemplation. A moment later the first sound in total silence has rapidly deteriorated into an outburst of laughter. The old man sighed and said,
- Oh, screw that bloody island of Leisia and particularly them Leisian twos!!
