End of Days, Part V

Since everyone knows that the Mayan Calendar will end this December, it is important to mail out save-the-date cards.  Otherwise, all your potential party guests will have long since made alternate doomsday plans by the time you send out the actual invitations.  And nobody wants to put all that work into a great end-of-the-world party and have no guests so up.  So in an effort to help you get a jump on those save-the-last-date cards, I've provided a few samples below:

• It's the last date you'll ever have to remember, so don't forget!  I'm hosting an End-of-the-Mayan Calendar Party this December the 21st.
• Roses are red.  Violets are blue.  When the world starts ending, I want to be hanging out with you.
• Before the world ends and the zombies start roaming, be sure to stop by for my End-of-the-World Homecoming.    
• Sure you could spend this December the 21st holding up in your basement bomb shelter, but wouldn't it be more fun to ring in the new world with friends, family, and a keg of beer?
