March 2nd marks the 109th anniversary of the birth of Theodor Seuss Geisel, aka Dr. Seuss, creator of The Cat in the Hat, Thing 1 and Thing 2 and an especially interesting substance called "oobleck." Hey, Sam-I-Am, pick up a book today and celebrate Read Across America Day in honor of this amazing, witty, flabbergastingly creative individual.  And you can read the stories behind some of his most famous books at Mental Floss.
