What's an expression/idiom you've learned or heard in a foreign language which sounds funny to you when interpreted literally?

Mine will always be the English idiom: "It's raining cats and dogs"

Every language is overflowing with idioms that only its speakers understand. I have always been interested in learning something like that. When you start learning a new language, you enter an unknown world filled with exciting information. Even if some languages belong to the same group and are roughly similar, it doesn't mean that they won't have differences. To learn a new language, you need to communicate with a native speaker. However, to learn the basics, a simple dictionary will suffice. I recently ordered a Dutch dictionary https://www.amazon.com/Dutch-Frequency-Dictionary-Vocabulary-Dutch-English/dp/9492637340 because I want to know the language. I'm at the beginning stage, so I think it will be enough for me.
