What is the difference between JFK (1960) and JFK (2004)?

John F. Kennedy had no problem with charisma, and a bad spine. John F. Kerry has a bad problem with charisma, and no spine.

Over the years, The Invitational has been accused of awarding prizes (such as they are) to political humor that tends to veer maybe a wee bit to the left. So, to compensate for any perceived liberal bias, The Empress decided this week to print only right- leaning anagrams in the results below. Nah, not really; that would have been wrong. In fact, it would have been impossible -- because there weren't any right-leaning ones to choose from: The spectrum of the political anagrams submitted ranged from Gentle Tweaking of the Administration to Raving Leftist Screed.

This week's contest, suggested by Mark Cackler of Falls Church: See if you can give us some Fair and Balance -- send us conservative- leaning humor in any of the following genres:

(1) Knock-knock jokes; (2) limericks; (3) "how can you tell" riddles; (4) "what's the difference" riddles; (5) four-line rhyming poems.

Jokes about Bill Clinton's sex life do not qualify; they transcend ideological barriers. And needless to say, joke plagiarists will be abused and humiliated.

First-prize winner receives the Inker, the official Style Invitational Trophy. First runner-up wins an autographed copy of "The Hype About Hydrogen" by Joseph Romm, a longtime Loser who donated his new book as a prize in a desperate attempt to see it mentioned in The Washington Post. (Joe is perhaps more famous for having also donated as a prize, in 1995, his underpants.)

Other runners-up win the coveted Style Invitational Loser T- shirt. Honorable mentions get one of the lusted-after Style Invitational Magnets. One prize per entrant per week.

Send your entries via fax to 202-334-4312 or by e-mail to losers@washpost.com. Deadline is Monday, May 24. Put the week number in the subject line of your e-mail, or you risk being ignored as spam.

Entries may be edited for taste or content. Results will be published June 13. 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 Scott Campisi of Wake Village, Tex.

Report from Week 554, in which we asked you to create an anagram for any text about a person or event recently in the news. Many (but not all) of the winning entrants used the suggested Anagram Artist software -- as did many of the losing entrants. As we found out right away, that program will count letters for you, and even suggest words, but it's still really hard to write a good anagram on it.

Once again, the people at www.anagrammy.com invite you to enter your Invitational entry -- winning or not (and other anagrams) -- in their monthly contest. And you even get to vote for the winners.
