"It is a symbol of Irish art. The cracked lookingglass of a servant." -- James Joyce
The English clearly have a different sensibility about what makes an item sound desirable than do Americans. For example, the other day, I was in a cafe that had named a sandwich on its menu, "The Crusty Bloomer." I can't ever remember, or easily envision, an American restaurant doing the same kind of thing, for example, christening a chocolate desert "The Runny Poop."
