It's a small world, all right. Less is more, small is beautiful, little things mean a lot -- so take a little time, get down and have yourself a merry little weekend. You don't have to go to Micronesia or even Little Rock. We're talking short-range plans here. Take a quick spin on the Little River Turnpike, pack a picnic to Little Falls, buy a ticket on the Short Line Railroad. Take along the little woman -- and the little darlings, the little dickens, the little shavers. It's a Wee-kend. Drive an MG Midget or a Honda Mini. Take a swing at miniature golf or a turn on a minibike. Zip over to a Little League game and cheer for the shortstop. Look for a fairy ring in the forest and the Little Dipper in the sky. Tune in a shortwave radio or turn on the minicam news. Browse through the minimalists at the National Gallery, or the miniatures at the National Portrait Gallery. Visit the bonsai garden at the Arboretum and keep your eyes out for a Shortia galacifolia. Sharpen your binoculars for a least bittern. Drive out to the Gettysburg Miniature Horse Farm and let the kids go eye-to-eye with the equines. Hire the Mini-Bus Limousine Service to take you to the Dolls' House and Toy Museum. Stop by the Little Hut for penny candy. Try your hand at bridge and bid a little slam. Cut for little casino. Petitpoint a pincushion. Sit in on small-claims court. Take target practice with a snub-nosed revolver. Make an appointment with your shrink to talk about your shortcomings. And don't mince words: Are you small-minded, short-tempered and short-sighted? Do you cut people off? Fall back on small talk? Support the Little People's Caucus: Send a half-sheet to Rep. Barbara Mikulski (she has to get on a soap box just to reach the microphone). Music to play: Little Richard, Little Eva, Little Anthony, Little Stevie Wonder, Little Feat, Tiny Tim, Little River Band, Small Faces, Bobby Short. "A Little Night Music." Randy Newman (honorable mention for "Short People") and Paul Williams. "The Minute Waltz" and The Unfinished Symphony. Now rest for a hemidemisemiquaver. Songs to sing: "There's a Small Hotel," "With a Little Bit of Luck," "Babes in Arms," "Thank Heaven for Little Girls," "In the Wee Small Hours of the Morning." "Little Brown Jug" makes "Tiny Bubbles." Where to eat: the Little Tavern, the Inn at Little Washington, Petitto's or the Tastee Diner -- the area's most famous short-order house. What to eat: littleneck clams, shrimp, small-mouth bass, petit fours, petit pois, tater tots, mincemeat pie, short ribs and shortcake. Cherry tomatoes and bantam corn. Spoonsize Shredded Wheat and Kraft Miniatures. Or whittle your waistline with a half- portion of shortnin' bread (this is a day for small victories). Read "Diet for a Small Planet." Feeling a tad run down? Take your minimum daily vitamins. Brevity is the soul of wit: Study shorthand. Get a trim or a pixie cut (a little dab'll do ya). Buy a few buds from Small & Sons flowers or a knick-knack from the Tiny Jewel Box. Go to a Baskin-Robbins and get a half- teaspoon taste of all 32 flavors. Have a wee dram -- buy liquor in 11/2-ounce bottles, or beer in 7-ounce "ponies." Watch "Little House on the Prairie," where the onetime Little Joe calls his daughter "Half Pint." A miniseries, maybe, or a short subject. And watch it all, of course, on a 4-inch Sony portable. Start a Little Rogues' Gallery: Prepare thumbnail sketches of Toulouse-Lautrec, Fiorello "Little Flower" La Guardia, Tom Thumb and Napoleon (affectionately known as the Little Corporal). "Little Boy" was the code name for the 10,000-pound atomic b and a smidgen of that). What to read the small fry: the Nutshell Library, "The Little Mermaid," "Thumbelina," "The Borrowers," "The Little Engine That Could" and "Little Red Riding Hood," "The Little Prince" and "The Little King." "The Five Little Peppers and How They Grew." Anybody's collected short stories. In a pinch, Reader's Digest condensed novels or Cliff Notes. Movies: "The Incredible Shrinking Woman," "Snow White and the Seven Dwarfs," "Darby O'Gill and the Little People," "Small Change," "The Terrors of Tinytown." "Little Caesar," "Little Big Man," "Little Murders" and "Ten Little Indians." Charlie Chaplin as the Little Tramp. And a Shirley Temple Festival: "Little Miss Broadway," "Little Miss Marker," "The Little Colonel," "The Little Princess," "The Littlest Rebel" and "Wee Willie Winkie." Famous sidekicks: Little Beaver, the Little Green Sprout, Little John, Boy. Famous know-it-alls: Little Orphan Annie, Little Lord Fauntleroy and the Little Shepherd of Kingdom Come. Cartoon classics: Li'l Abner, Little Lulu, Wee Folks, "Three Little Pigs" (Oscar winners of '33). Popeye, incidentally, started out in 1919 as a character in "Thimble Theatre." So bring your weekend down to size. Remember: Small, and the world's small with you.
