Instant Twanswations

The Dialecticizer, by Rinkworks, has been one of my favorite fun tools for years. It can take any phrase, such as, "Gene, it's about time you got up for your exam, since it starts in half an hour!" and converts it into
(1) Redneck: "June, it's about time yo' got up fo' yer exam, on account o' it starts in ha'f an hour!"
(2) Jive: "Gene, it's about time ya' gots down fo' yo' 'esam, since it starts in half an hour! Right on!"
(3) Cockney: "Gene, it's about time yer got up for yor exam, since it starts in 'alf an 'our! Right!"
(4) Elmer Fudd: (my personal favorite) "Gene, it's about time you got up fow youw exam, since it stawts in hawf an houw!"
(5) Swedish Chef: "Gene-a, it's ebuoot teeme-a yuoo gut up fur yuoor ixem, seence-a it sterts in helff un huoor!"
(6) Moron: "Gene, uh uh uh, it's bou' time you got up f' your exam, siss it starts in half an hour! Doihh!"
(7) Pig Latin: "Enegay, it'syay aboutyay imetay youay otgay upyay orfay youray examyay, incesay ityay artsstay inyay alfhay anyay ourhay!"
and
(8) Hacker: "gene,, it"z about time ypou got up fro yor exam, snice it starts In 4hlf aN HOur!!!!!!!1 AACX)R OYUUUuUUU bceauiz you arfe lame"

You can do entire paragraphs.
Here's one from an anti-walmart page:
Original: "Wal-Mart has become much more than just a small corner store in rural America. In the past 10 years, Wal-Mart has grown into the largest retailer in the world -- number 1 among the Fortune 500 -- and is America's largest employer. With more than 1.4 million employees and over $10 billion in profits, Wal-Mart is a giant company with giant responsibilities. First and foremost, Wal-Mart has a responsibility to all Americans to set the standard for customers, workers and communities, and to help build a better America."
And converted for you to Elmer Fudd (funniest when read aloud):
"Waw-Mawt has become much mowe than just a smaww cownew stowe in wuwaw Amewica. In the past 10 yeaws, Waw-Mawt has gwown into the wawgest wetaiwew in the wowwd -- numbew 1 among the Fowtune 500 -- and is Amewica's wawgest empwoyew. Wif mowe than 1.4 miwwion empwoyees and ovew $10 biwwion in pwofits, Waw-Mawt is a giant company wif giant wesponsibiwities. Oh, dat scwewy wabbit! Fiwst and fowemost, Waw-Mawt has a wesponsibiwity to aww Amewicans to set the standawd fow customews, wowkews and communities, and to hewp buiwd a bettew Amewica."

They also let you enter a URL and it will convert the text on the website to the language as well.
