Theodore Geisel, better known as Dr. Seuss, was even more prolific than we thought. The beloved author of "Cat in the Hat," "Green Eggs and Ham," and "Oh, the Places You'll Go" (a required gift for every college graduate) also penned the beginning of another book that never saw the light of day. The unfinished manuscript for "All Sorts of Sports" recently went up for auction and fetched an impressive sum.

The 19-page manuscript, in which a wishy-washy athlete named Pete tries a hundred different sports, dates back to the '60s and sold for $34,004 to an undisclosed buyer. According to the auction house, the first seven pages of the manuscript were handwritten by Seuss, while the remaining pages were penned by an assistant. Doodles by Seuss were also included. According to NPR, the good doctor's writing assistant had possession of it before deciding to put it up for auction.

The L.A. Times points out that it may have been this bit of self-editing on the part of Seuss that set him apart. Clearly, he was good enough to know that not everything he wrote was worthy of his name....
