Similar idioms in other languages

I was talking to someone recently whose second language was English and they were trying to describe someone who was acting like a "Bull in a China Shop"

They used a phrase like "Elephant in a porcelain factory" (or similar) and later I was expressing my amusement at that to another non-English speaker and they said that that was very similar to the idiom used in their language (Polish).

I thought that I would do some research on how many similar idioms there were with similar meanings in other languages, any ideas as to where to start?

French : Un éléphant dans un magasin de porcelaine ( China shop)

[Wuisi]

Español: Como un elefante en una cacharrería.
There are a lot involving animals: Un burro en un garaje (a donkey in a mechanist's, that is absent-minded and oblivious), Un pavo en navidad (a turkey at Christmas, that is, afraid and suspicious), Un cerdo en un charco ( a pig in a pond, enjoying himself and happy as you can be); we even say 'Tienes el mismo cerebro que un caballo' (You have horse's brains, that is, just enough not to poo during a parade...) They are quite funny.

Same in Russian: Слон в посудной лавке = An elephant in china shop. I would be curious to know in which language it started, and why? Anyone was able to find the roots so far?

[Torben]

In danish: som en elefant i en glasbutik
----------- like an elephant in a glass store

Do any of you use 'eat my hat'? Apparently, it occurs in some other languages.

[atlaisha]

What does it mean?

[Torben]

I'll eat my hat if I'm wrong = to do something impossible (eat a hat) if you are wrong.

"eat my hat" is a very common saying in danish. "aede min hat".

Got my own saying, about something that's very difficult:

"It's like, getting a camel through a keyhole"

[Tdol]

We say easier for a camel to go through the eye of a needle, which is from the Bible.
