Here's an example of the kind of email you'd get:
Nobodaddy
[NOH-boh-dad-ee] a word used by William Blake as a disrespectful name
for God. By extension, used for someone no longer admired. A blend of
nobody and daddy.
See? Wouldn't your friends/family/co-workers/fellow inmates at the asylum be impressed if you used that word in conversation? You, too, can get a weird and wonderful word a day delivered right to your e-mail inbox, for the low low price of NOTHING! That's right -- you get this mind/vocabulary/conversation/popularity enhancer absolutely FREE!
Can't beat that with a stick.
