1. You look cute in 'em (to some of us, that is) Ohh, yeah.
2. The necktie offers an infinite form of variety: patterns, colors, scenes, fabrics (finite set, I suppose), logos, art-on-a-strip-of-cloth Glad you didn't restrict that to "pretty".
3. It's phallic ? Hrm...
4. Some people are impressed that you can tie 'em at all It does take a bit of know-how. I actually learned to tie a necktie from fastening a saddle girth.
5. Life is a series of knots to be tied and untied Woo, profound!
6. It's a giant arrowhead Ohmigawd--pointing to what, dare I ask??
7. It's a bow on a package of male I LOVE it!
8. You can honestly say when wearin' 'em and want to get out of something, "I'm all tied up now" Ha!
9. It's a rocket Er-- ?
10. And (to misquote Faldage): It cuts off the supply of blood to your brains thereby leveling the mental playing field ...and sending it to... No, I won't say it!

=========================================================
stales, here in the south, we often do say necktie. We may be somewhat behind other folks, in still saying that. If I say just 'tie', I want to be sure my hearer understands from my context that I'm not talking about, say, a garbage tie. If my husband were to say, "Bring me a tie", I'd need to know whether he was getting ready to go to work, or to take out the garbage. Though the Christmas necktie his brother fobbed off on him would be put to better use tying up the trash, I think...
