What is the difference between Enron and a salmon? They both smell fishy, but you can't buy a piece of salmon for thirty cents.

This Week's Contest: Take any two nouns that appear on the front page of today's Washington Post (or today's home page of washingtonpost.com) and explain how the nouns differ from each other, as in the example illustrated above, which was taken from a recent Page A1. You can use proper names, and you can also include any modifiers that appear with the noun. (As in, say, "large, steamy chalupas.") First-prize winner gets a genuine antique 1968 Democratic Campaign Bottle, still in its box, in the shape of a donkey with Hubert Humphrey's face. This is worth $50. First runner-up wins the tacky but estimable Style Invitational Loser Pen. Other runners-up win the coveted Style Invitational Loser T-shirt. Honorable mentions get the mildly sought-after Style Invitational bumper sticker. Send your entries via fax to 202-334-4312, or by e-mail to losers@washpost.com. U.S. mail entries have been canceled due to rabid, spit-flying fanaticism. Deadline is Monday, Feb. 25. All entries must include the week number of the contest and your name, postal address and phone number. E-mail entries must include the week number in the subject field. Contests will be judged on the basis of humor and originality. All entries become the property of The Washington Post.

Entries may be edited for taste or content. Results will be published in four weeks. No purchase required for entry. Employees of The Washington Post, and their immediate relatives, are not eligible for prizes. Pseudonymous entries will be disqualified. The revised title for next week's contest is by Chris Doyle of Burke.
