Tim Burton apparently agrees: Spite is the best reason to do anything

From the Wikipedia entry on Jack Nicholson (and confirmed on IMDB and several other independent sources):

In 1996, Nicholson collaborated with Batman director Tim Burton on Mars Attacks!, pulling double duty as two contrasting characters, President James Dale and Las Vegas property developer Art Land.

At first studio executives at Warner Bros. disliked the idea of killing off Nicholson's character, so Burton created two characters for Nicholson instead and killed them both off.

I suspect that Tim Burton and I would get along rather well.
