Get the DAY-X mug.
X-Day (the SubGenius rapture), voted Time Magazine's 'Scam of the Century', was supposed to have swept the SubGenii from the earth on July 5th, 1998. This was a faith-shattering event for many x-ists, who were not loaded into the pleasure-ships filled with sex-goddesses. Though it hasn't stopped the SubGenii from gathering every subsequent 5th of July devivals, in hopes that they may have been off by a few years.
I hope that there's a lot of bug-porn on those pleasure ships, come x-day.
