You don't have to read this; I just added it in case you were interested.
Also of possible interest: the NPR informal roundtable on reading Moby-Dick, in which one segment compares Ahab to Bill Paxton in Twister: http://www.npr.org/blogs/monkeysee/2010/06/18/127933161/-moby-dick-we-ve-come-to-the-en. . A sample:
I have to say, I really thought that Ahab and the whale were going to realize that they loved each other all along.
Linda: And then they'd kiss at the end.
Marc: They SORT of did that.
Linda: They were bound together.
Marc: "With this rope I thee GRRRRRK!"
