Yup, that too, we also have a lot of expressions involving apples; a small kid is said to be "as tall as three apples". Someone with a nice face, you say they have a nice apple (can also be said for someone who is too kind for their own good). When someone faints, we say they "fell in the apples". To describe a useless endeavour, you say you did "all that for apples". A lazy, dull person is called a "watered-down apple". Last but not least, there's the "discord apple", a bone of contention between two people (this one comes from Greek mythology, with the story of Paris - the Greek hero, not the city) 

As for Canadians, they would say "singing an apple", which an euphemism for flirting and courting someone.

We also share a few with our anglo-saxon friends; adam's apple, an apple a day keeps the doctor away (if you know how to aim), apples falling far from the tree...

I could say the French expressions are better than the English ones, but that would be comparing apples to oranges 🤷🏻‍♂️

I’m born and raised Canadian, and I’ve never heard of singing for apples
