Today marks the birthday of Theodor Seuss Geisel, AKA Dr. Seuss! The fanciful author who gave us many memorable tongue twisters such as Horton Hears A Who, Green Eggs And Ham, and The Cat In The Hat would have been 105 years old today. Interestingly, Dr. Seuss had a three-legged dog as a child. Rex, a Bulldog, was his faithful companion during his childhood in Springfield, Massachusetts. Perhaps Rex provided inspiration for some of Seuss' unique canine characters... Go, Dog. Go!
