Courtesy of Wikipedia: apparently Häagen-Dasz sued a Swedish brand of ice-cream called "Frusen Glädje" in 1980-something, for lookalike "Scandinavian branding".
It's just that "Frusen Glädje" actually IS real Swedish, and means "Frozen Joy" (or "gladness").
Which is sort of like the art gallery Louisiana suing the state of Louisiana
