The t-shirt deal of the day over at RIPT Apparel is a mash-up of Doctor Who and Dr. Seuss’ Horton Hears A Who called “Horton Hears a Doctor.”

The tee, by artist rtofirefly, went on sale at RIPT today, Thursday, March 31, 2011, at midnight CST, and will continue for 24 hours from then, and once it’s over, it will not be sold on the site anymore.

The next Dr. Seuss property to be shipped off for a cinematic treatment will be The Lorax. The movie is expected to be another computer animated 3D movie, and will be produced by Universal Pictures and Illumination Entertainment. This movie will be the fourth Dr. Seuss adaptation: the first being Ron Howard’s live-action adaptation of How the Grinch Stole Christmas with Jim Carrey; the second being The Cat in the Hat with Mike Myers; and the third switching over to computer animation with Horton Hears A Who! again with Carrey and Steve Carell. Chris Meledandri of Illumination and Seuss’s (Theodor Geisel) widow Audrey Geisel will be among the film’s executive producers.

Cinco Paul and Ken Daurio are currently writing the script, as well as co-directing the movie along with Chris Renaud. All three men worked together in one aspect or another — whether it was storyboard art or writing — on Horton.

Out of all of the original Dr. Seuss books and cartoons to be adapted to movie form, Horton Hears A Who! is the first to go all CG, differentiating itself from The Grinch Who Stole Christmas and The Cat in the Hat.

The movie follows Horton (Jim Carrey), a friendly and innocent elephant teacher who thinks that he hears a noise from a small speck on top of a small flower and comes to believe that this small speck holds a world of tiny people, to which most of the other animals think he’s absolutely nuts. In time, he finds a way to communicate with the Mayor of this tiny world (Steve Carrell), known as of Whoville. The Mayer tells Horton that his continuous movement is messing up the little world’s climate and will eventually destroy everything. This sets Horton off on a journey to find the perfect spot to safely put them while trying to avoid an extremely tyrannical soccer mom kangaroo (Carol Burnett), her hired vulture (Will Arnett), and a grab bag of other speedbumps along the way.
