crazy as a loon; loony. The common loon (Gavia immer) is noted for what one expert calls its “mirthless laughter, a high, far-crying, liquid tremolo that sets your spine atingle.” This water bird’s name may come from the Dutch loen. The loon has noth- ing to do with the word loony, for “crazy,” which is a shortening of lunatic, but it does give us the expression crazy as a loon. |
