Tornadoes: Help prevent trailer park overcrowding. Athletes Acting Like Jerks: Nike execs have to swallow their swoosh. Illiteracy: Guarantees a steady supply of guests on Jerry Springer.

This Week's Contest was suggested by Jean Sorensen of Herndon, who wins a can of a Japanese coffee drink named "Mr. B.M." Jean suggests that you supply a silver lining for any scourge or social ill facing America or the world. First-prize winner receives what appears to be a genuine 1964 Russian lapel pin endorsing the presidential candidacy of Barry Goldwater and William E. Miller. We declare this to be a value of $100.

First runner-up gets the tacky but estimable Style Invitational Loser's Pen. Other runners-up 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 249, 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: losers@access.digex.net. Internet users: Please indicate the week number in the "subject" field. Entries must be received on or before Monday, Dec. 29. Please include your address and phone number. Winners will be announced three weeks from today. Editors reserve the right to alter entries for taste, humor or appropriateness. No purchase necessary. Blockage or dysfunction of the eustachian tube is believed to be the pathophysiologic basis for purulent discharge from the ear, suggesting labyrinthitis, fistulization and Beland's Syndrome, which causes extreme pouting and crankiness in adults. Next week: J.D. Salinger Ear Credit. Employees of The Washington Post, and members of their immediate families, are not eligible for prizes.

Report from Week 246,

in which we showed you several contraptions and asked you to tell us how they worked. Niels Hoven of Silver Spring wins a T-shirt for a bawdy entry that we briefly considered printing until we were informed that the consequences would involve (1) published apologies to the readers by Donald Graham and (2) an abrupt termination of our employment, possibly via the discharge of a firearm.
