Today is the ninth day of the ninth month of the ninth year of the century. So, it's pretty obvious you should throw a party. And also because you're probably a little depressed, because summer is over and it's gray outside and it's only Wednesday and the beginning of next summer is nine long months away, so why not celebrate a little bit?  Click below for our tips on how to throw the best 9/9/09 party in history!

-

• Invite nine friends over. Come on, you have nine friends, right?

• Mix a drink with no fewer than 9 ingredients. This will no doubt be pretty potent.

• Have nine rounds of said drink.

• At this point you will probably be feeling pretty ready for a game of 9 Minutes In Heaven.

• Wasn't that fun? How about a round of "99 Bottles Of Beer On The Wall"?

• All your guests are pretty tipsy, right? Now is the time to dazzle them with geeky math facts! For example: 9/9/09 falls on a WEDNESDAY in SEPTEMBER....and both of those words have 9 letters! Amazing!

• Also, it's the 252nd day of the year. 2+5+2 equals, you guessed it, 9!

• Is it 9:00 pm yet? In that case, Republican politicians want you to sign on to Twitter for "the largest Twitter Tea Party ever". You'll be too drunk to notice that the concept of a Twitter Tea Party doesn't make any sense whatsoever!

• You should be done Twittering by 9:09 (and, really, it shouldn't even take nine minutes...), so at that point it'll be a good time to turn on some Beatles music; their full music collection comes out today, digitally remastered and everything!

• Did all that groovy music make you feel contemplative? Then how about sharing a personal story with Matthias Klucker, who is using this day to collect stories from around the world and compiling them to make "A Day In The Life Of The Planet".

• You're feeling soooooooo good now, right? Why not do something crazy? Like really crazy? Like...go get married crazy? 9 is a lucky number, and in Las Vegas you can get married for $99.09...
