Tie jokes abound. After all, a clean tie always attracts the soup. Or what else are ties for? It's for decoration, of course. Always been that way, according to The History of Ties. In short, a tie is meant to complement your clothes, which in turn compliments your outlook in life. Unless you're wearing a long face, in which case "your views may be as narrow as your tie," as Bernard Herrmann once said.
