Brandon Lee, but he's dead. I'd still like to meet James O'Barr. My desire to meet Weird Al Yankovic has kind of diminished for me since he got married.
If you're talking about everyday people, I'd like to meet some other people who's greatest philosophical influences are Robert Heinlein and Ayn Rand. So far, I haven't met too many other people who are into BOTH of those authors.
I DON'T want to meet anybody who's interested in my age, sex, or location, or who writes "nebody" instead of "anybody". Leet speak is only amusing when it's intentionally ironic.
