I agree that the easy answer would be Babe Ruth, Picasso and Shakespeare. These men didn't really change the world in respect to technological or scientific realms, but they certainly brought more pleasure to humanity than say Einstein, Lincoln and Plato.
After reading the Gore Vidal biography on Abraham Lincoln I've infered that he never cared the freeing of slaves. His main objective was to maintain a power union of states. You take this key trait away from his historic reputation and he's no more than another U.S. President who stuck his nose in someone else's business. I'd say, bump him
Shakespeare was just a playwrite. He inspired millions of boring, pretentious, and snobby people to believe that they knew more about art and literature simply because they could recite his sonnets and monologues. It's true that he plagarized (i.e. STOLE) almost all of his plotlines, and characters from earlier works. Some of those works came from his peers. His plays alone may be revered, but he could also get bumped and it wouldn't make much of a difference.
Babe Ruth was a fat, selfish, slob. He hit 60 home runs when it was unheard of to hit more than 25 in a single season. That's a novelity in the longterm of humanity. Need I say more? Bump his fat skeleton out of notoreity.
