Improvalooza 1997 Local improv artists turn the art of razor-sharp comic timing into a team sport as they warm up for the National ComedySportz Tournament. Their goal? A prize of no less stature than the Meaningless Cup. Houston placed third in the nation last year, but this year, with performers holding such names as Lucian "Splooshian" Smith, and Dianah "Delooney" Dulany, we can't help but come out undisputed champions, rulers of the meaningless universe. 8 p.m., Treebeards on Market Square, 315 Travis, 521-2226. $10.

The Mikado Only the imperialist Victorians could gleefully appropriate medieval Japanese culture to spoof 19th-century British manners and morals with such lighthearted cultural insensitivity. But that's exactly what quintessential Victorians W.S. Gilbert and Arthur Sullivan did in their wickedly witty, politically savvy and musically ornate opera The Mikado. Legend has it that Gilbert's inspiration for his most famous opera fell, quite literally, at his feet. Brainstorming for operatic ideas, he tromped his big English shoes across the floorboards of his quiet study. A Japanese executioner's sword decorating his wall clattered to the ground before him, and in that moment the muse struck. What came afterward was the creation of some of light opera's funniest and most famous characters -- including the deliciously beautiful Yum-Yum and her handsome lover, the decidedly unfortunate Nanki-Poo, heir to the Japanese throne. There is also Ko-Ko, Lord High Executioner, and of course the Mikado himself; both do everything oldsters do to get in the way of young love before all comes out fine in the end. Thru July 27. 8 p.m. tonight (see Thrills for other dates and times). Wortham Center, Cullen Theater, 500 Texas, 236-8310. $12-30.
Japanese Bookbinding and Wall Stamping The elegant art of bookbinding is so demure that most of us aren't even aware of it when we are holding a book in our hands. Discover the secrets of this modest art in a demonstration given today by Darla Hartmann, the visual artist who founded Artists Bookworks Houston. In addition, Lyle Barrett, owner of P.O. Box Rubberstamps, will demonstrate the rowdier craft of rubber stamping. Learn to stamp wood, walls, furniture -- anything but pets, spouses and children. Bookbinding demo at 10:15 a.m. & 12:15 p.m.; wall stamping demo, 11:15 a.m. & 1:15 p.m.; stamp-making demo at noon. Heights Pavilion, 244 West 19th St., 864-0656 or 861-3411. Free.
A Glenn Miller Evening What better way to enjoy an old-fashioned good-time Saturday night than with two ballrooms filled with foxtrotters and the luscious long sound of big band music? Imagine the twine of the lonely clarinet snaking down your spine, affording you no choice but to join the others twirling on the glossy floor. The lights are low, but the setups for sale on the side make the night glow bright once you've added a shot from the flask you've brought. Or maybe the music and dancing alone are enough to make the night shine. It's all legal and perfectly healthy (provided that flask isn't too big). Join Billie Ledbetter and his orchestra and dance, as they say, the night away. BYOB, 8 p.m.midnight, West Houston DanceSport Center, 14919 Bellaire Blvd., (281) 933-9970. $10, singles; $18, couples.
