Who cares if the owner of the "Tall and Fat" clothing empire never finished high school? Thornton's pockets are deep enough to buy a ticket to class and hire NASA to do his homework!

Now, he'll have to hit the books -- instead of his bank account -- or go back to being the world's wealthiest dropout!
