Ah, the 25-hour day. For everyone who has ever complained that there's not enough time to get everything done, today was made with you in mind. Sure, it's just a little accounting flimflam that simply returns the hour we lost in back in April, but why think about it that way? Instead, treat it as a 3,600-second windfall and take full advantage of the extra time. Need a few suggestions? We're only to happy to help:

* Sleep. An obvious start to any serious list.

* Buy a Breathalyzer. Find out how many drinks it takes you to reach 0.03. Call the D.C. cops and turn yourself in.

* Run in to every free museum on the mall. Brag to your parents about how you took advantage of Washington's great cultural offerings.

* Read the Sunday Source. Spend the remaining 47 minutes on Sudoku (see Comics).

* Call friends in Arizona, Hawaii and Indiana. Make fun of them for not getting an extra hour.

* Dance as if no one were watching. But first, make sure that no one is watching.

* Devise a strategy for selecting winning Powerball numbers. Or just call Sen. Judd Gregg's office for recommendations.

* Watch your wedding video. Do this without criticizing your appearance. (Bonus points if you don't make your spouse watch with you.)

* Visit a palm reader or a psychic. They'll be expecting you.

* Eat all of the Halloween candy. Save the carrot sticks for the cute little trick-or-treaters tomorrow.

* Have a romantic dinner with your partner. Or, you know, just skip the dinner altogether.

* Think of someone to nominate for the Supreme Court. Any old friend will do.

* Make cookies. Send some to us: 1150 15th St. NW.

* Come up with an idea for a magazine. Modern Ferret already is taken.

* Order your free credit report. Spend the rest of the hour shopping online.

* Go to open houses. Exclaim "I'll take it!" as soon as you walk in the door. Realtors love that.

* Write a limerick. Begin with: "There once was a 'Skin named LaVar."

* Go for a walk. Stun your neighbors by saying hello and smiling. (But don't smile too much -- that's creepy.)

* Write a list of all the things you could have done with your extra hour.

Did we mention sleep?
