This is from a contest in Oxnard, California. The requirements were to use the words Lewinsky and Kaczynski (the Unibomber) in a limerick. Here are the top 3:

Winner:

There once was a gal named Lewinsky
Who played on a flute like Stravinsky
'Twas "Hail to the Chief"
On this flute made of beef
That stole the front page from Kaczynski.

First runner up:

Said Bill Clinton to young Ms. Lewinsky
We don't want to leave clues like Kaczynski,
Since you look such a mess,
Use the hem of your dress
And wipe that stuff off of your chinsky.

Second runner up:

Lewinsky and Clinton have shown
What Kaczynski must surely have known:
That an intern is better
Than a bomb in a letter
Given the choice of how to be blown.
