Hello Skvodo, and welcome to Tatoeba.

What you contributed is not a sentence but an expression. Here we need full sentences, so you should change it to form one (adding a subject, etc).

Pearls before swine ?

http://en.wikipedia.org/wiki/Pearls_Before_Swine

the English/French/Japanese do not match with the Italian/German couple.

the English could be reverted to "pearls" and the French and Japanese split off.

I unlinked the french/english/japanese from the italian sentences > the french sentence is not an idiom, but only a "literal" translation of the english sentence.

Ne jetez pas de poires aux cochons - the French sentence is about pears.

Не мечите бисер перед свиньями. - The Russian sentence is about pearls. I've just unlinked it.

I liked the typo in the English sentence. Worth leaving it here as is as a joke. I've translated it literally into Ukrainian.

EDIT: Also unlinked No arrojeis perlas a los cerdos.

Sure, someone can literally die because the followed the advice and didn't cast any pears before swine.

There should be a skull and crossbones warning on the Tatoeba sauce.

O my, some answers given to that exam question:
Eels, boars, sows, an eye, socks, the weather, grandpa. Ts ts.

@deniko, they would die because they refrained from casting pears before swine, when it was really pearls that they should have avoided throwing. After one of the pigs choked on the jewelry, its enraged brethren would get their revenge by sneaking into the house and spiking their owner's tomato sauce with poisonous mushrooms. Humorous to some, but deadly to the owner. Don't let that happen to you.

(When I left my earlier comment, which I have since deleted, my interpretation was incorrect because I failed to notice the "don't" in the original sentence. Such inattention can also be fatal.)

Alan, thanks for that, I stand corrected and I humbly admit the advice is life-threatening.

And thanks for notifying me you'd deleted your previous comment. I wish that was an automatic feature.

@deniko, I agree.

@brauchinet, eels can be quite slippery, and it can be dangerous for humans if you cast eels before swine and then leave them on the barn floor. Fortunately, pigs, for the most part, have rather steady footing, so they should be safe.
