Today's Word of the Day from dictionary.com was:

evanescent \ev-uh-NES-uhnt\, adjective:
Liable to vanish or pass away like vapor; fleeting.

The first thing I thought of was that band, Evanescence (or however they spell it). I don't think I've ever even listened to them, but since they're the sort that lives and dies by MTV'S Total Request Live (I can think of three things wrong with that name), basically implying with your name that you're going to be a one-hit wonder is somehow apropos.
