Reading via mastodon translate a thread by a French poster about recent actions by Macron and partway through got slapped in the face with the discovery that "I'll eat my hat" is an idiom in France as well as America ("Bon, je mange mon chapeau, et c'est pas très bon.")
Is this… how universal is this? Do they eat hats in Germany? Russia? What percentage of earth has a local-language idiom for eating hats?

Census from responses:

Eat hats: English, French, Norwegian, Swedish, Danish*, Icelandic, Hungarian, Finnish, Estonian*, Hebrew

Contradictory data re: hat-eating: Dutch

@mcc You definitely eat your hat in Hebrew.
