"Never trust a man who doesn't part his name in the middle"! Love that line, even if it isn't quite fair, since there are probably some great people who have horrid first names. But I guess they could just leave off the initial and go by whatever name they really use.
Personally, I'm rather fond of all my names, like Bilbo in the Hobbit. (After the escape from Mirkwood, he added "Barrel Rider" as one of his middle names.) So far, I've collected Timothy Michael Brendan Feldmann O'Reilly. Timothy Michael my parents gave me; Brendan I took as a "confirmation name" when I was 12 or so. (If you want to know what that is, google for it.) Then when I got married, I took my wife's maiden name as my middle name, so my legal middle initial is now F instead of M. And that's probably more than you wanted to know.
