This is great! On minor thing: you should scroll to the top of the page when the next button is clicked.

I found some not so terrible domains that are actually available:

repofire.com - Sounds like one of those named security exploit websites

startrekfirstcontact.com - Need I say more?

mscave.com - Man cave for the misses

mailomega.com - Ship via USPS, UPS, FedEx, DHL and more!

healthwestern.com - Sounds like a legit business

rethical.com - Tethics but with an R

shopfitr.com - Web 2.0 clothes shopping

cokego.com - Coke in an easier to carry can so you can do cool stuff

xscut.com - As seen on TV exercise machine or diet pill

coughbank.com - What were they thinking?

blingstack.com - The latest craze in web development: bash, linux, indigestion, netcat, and ghostscript

bankwestbank.com - Banking services by the Department of Redundancy Department

myonefamily.com - Anti DNA testing lobby group

itsorigin.com - Prequel to It the movie

awayget.com - Vacations for dyslexics

I'll see myself out...
