Cows, bearing anti-EU banners, graze in a polder. Caption informs us that the Dutch word for "moo" is the same as for "boo" (as in jeering).

I've been looking for something to replace the dreaded hissing that college-educated young people, especially women, seem to have adopted as their favorite jeer. I hope this catches on.
