Moby Dick is definitely a sperm whale, but he is definitely also white. I know because I've read the book and there are seemingly endless chapters on the subjects of both sperm whales and the color white. Seriously.
Regarding alternatives the only ones close are William II King of Wurttemburg, Wilhelm zu Wied (Prince of Albania) and Władysław Wróblewski acting Prime Minister of Poland, but no other presidents.
Also, describing Woody's laugh is relative--some people think it's hilarious.
