As the 2017 version of the movie It (in Hebrew, זה) has generated clown terror around the world with Israel being no exception, I’ll take this opportunity to remind at least some of you of another movie from about 30 years ago: Child’s Play, rendered in Hebrew as משחק ילדים
This expression existed even before the movie did.
Here’s an example:
Meteorology (forecasting) is not child’s play.
The word משחק
משחק ילדים also means a children’s game.
