Week 175: Fossil Fools. A tree-shaped car freshener. A live cockroach. Mount Rushmore. A bowling trophy. A computer mouse. A copy of today's Washington Post. Plastic bubbles used for packing boxes. A brassiere. A toilet. An umbrella. A D.C. taxi. A Swiss Army knife. A "WALK/DONT'T WALK" A Hefty bag. "Hmm. It seems to have been a primitive society, inasmuch as the most sophisticated surviving weaponry is sort of a double-barreled slingshot. Rocks hurled at a target in such close proximity suggests that this MIGHT be a two-headed species..." Today's contest is a variation on an idea submitted by several people over the last year. No one wins squat. The idea is that 2 million years from now, alien archaeologists visiting the desolatation of a once-inhabited planet known as Earth discover only one remnant of our civilization. Select one from the list above. What do the aliens mistakenly conclude about us from this item? (For extra credit, combine two or more into one conclusion.) First-prize winner gets "Butts Are Gross," a righteously indignant jigsaw puzzle featuring pictures of 11 animal tuchuses and a cigarette butt. Runners-up, as always, receive the coveted Style Invitational Loser's T-Shirt. Honorable Mentions get the mildly sought-after Style Invitational bumper sticker. Winners will be selected on the basis of humor and originality. Mail your entries to The Style Invitational, Week 175, c/o The Washington Post, 1150 15th St. NW, Washington, D.C. 20071, fax them to 202-334-4312 or submit them via Internet to this address: losersaccess.digex.net. Internet users: Please indicate the week number in the "subject" field. Entries must be received on or before Monday, July 29. Please include your address and phone number. Winners will be announced in three weeks. Editors reserve the right to alter entries for taste, humor or appropriateness. No purchase necessary. The Faerie of the Fine Print & the Ear No One Reads wishes to thank Robin D. Grove of Baltimore for today's Ear No One Reads. Washington Post employees and their families are not eligible for prizes. Report from Week 172, in which we asked you to write Poeds, poems consisting of one line of six one-syllable words, one line of three two-syllable words, one line of two three-syllable words, and a final line containing one six-syllable word. Poeds ("Poems by Ed") must contain at least one rhyme. Very hard contest. Much unseemly grousing and whining from regular entrants. Apparently, these individuals feel licensed to complain just because they have become virtually full-time employees of The Washington Post, albeit ones paid entirely in T-shirts, bumper stickers and the occasional Remote Controlled Fart Machine. Our favorite whine came from William Foster of Rockville, who finds us dreadfully lowbrow. William writes in iambic pentameter: 'Tis clear, Style Invitational decides its winners from submissions worst in taste. And queer: Style Invitational derides the brain, and lives with things below the waist. Hey, pal.
