Or in Scotland, a turnip - which would be the same as a fool. (Comes from Swedish turnip variety.) That takes me on one of my favorite lines in all Scots song, "Pirn Ta'ed Loonie." The singer's true love went off with a "lantern chaffed [jawed] soldier with a face that was as yellow as a biled Swadish neep." Well, doesn't look that funny but it's hysterical in the song.
