A less obtrusive version, designed for the sidebar. For better search engine baiting, I added the Bush family's last names. I removed the section about conservative commentators to keep the script a little cleaner. I also added a bunch of keywords.

For the document <head>:

<script type="text/javascript" language="JavaScript">
var bushPeople=new Array(
'George W. Bush',
'Jenna Bush',
'Barbara Bush',
'Laura Bush',
'Barney the dog'
);
var bushActions=new Array(
'humps',
'snelches',
'snowballs',
'cornholes',
'teabags',
'pole dances',
'alligator slaps',
'logjams',
'bagpipes',
'six-packs',
'fists'
);
var bushThings=new Array(
'on a webcam',
'midgets',
'horses',
'invalids',
'corpses',
'clowns',
'toothless old ladies',
'gay whales',
'altar boys'
);
</script>

For the document <body>:

<script type="text/javascript" language="JavaScript">document.write( "<h2 class=\"sidebar-title\">Random Bush Family porn</h2><ul><li>" + bushPeople[  Math.round(Math.random()*(bushPeople.length-1)) ] + "&nbsp;" + bushActions[  Math.round(Math.random()*(bushActions.length-1)) ] + "&nbsp;" + bushThings[  Math.round(Math.random()*(bushThings.length-1)) ] + "</li></ul>");</script>

And again, I'm open to suggestions.
