I second both of these, and add:
Mr. (Seth) Pecksniff (The Life and Adventures of Martin Chuzzlewit)
Buster Broadnax (The Color Purple), especially when I hear it as “Busta” in my head.
Guitar Bains (Song of Solomon)
First Corinthians Dead (Song of Solomon)
Draco Malfoy, the Harry Potter books
A Doper’s username just reminded me of two more:
Joe Buck
Ratso Rizzo
Seymour Glass
Big Ern McCracken
John Cocktoston (Fletch)
At the moment my favorite character name comes from The Bone Doll’s Twin, Tobin. It amuses me because I can’t help but think of the bridge in Boston, though it occurs to me that as a name it’s not necessarily pronounced Toe-bin, but could instead be Tob-in.
<hijack> So…from this very interesting selection of names people actually like, are Ready (so called from the mangling of the nickname Teddy) and West not-to-irritating/out there names for child characters? They’re the ones I’m toying with for a project I’m brainstorming. If it matters, Ready would be a ten-year-old boy and West his four-year-old brother.
I ask because I’m one of those people who finds twee names enough of a turn-off to stop reading something…</hijack>
He was Ernie Kovacs, though.
Hannibal Lecter. The name has crept into our lexicon.
The O’Hara sisters all had names that described their personalities: scarlet woma Scarlett, sullen Suellen, and caring Careen.
Krusty the Klown.
Yes, I didn’t mean to imply that he was a Bob and Ray character. It just came to me while I was on the same post.
My favourite has to be the Kzin Speaker-to-Animals.
No mention yet of Dr Who?
Two from Asimov:
R. Daneel Olivaw
Ebling Mis
Another Ian Fleming heroine:
Galatea (Gala) Brand (supposedly named after her father’s ship HMS Galatea).
Pratchett yet again : Cheery Littlebottom.
(Is anyone keeping track of which authors are featured most here?)
Actually for about 30 years he held the record for the most strikeouts during a career.
Terry Pratchett and Simon Green both seem to be doing well. Both have this thing for great names.
Speaking of Simon Green, I nominate just about every major player in the Nightside. And Owen Deathstalker, too.
Casanova Frankenstein
Seconded. A mate and I both agreed that it was the ultimate, untoppable character name. Except maybe for Dr. Evil, for obvious reasons.
General “Buck” Turgidson
Brigadier General Jack D. Ripper
Colonel “Bat” Guano
Major T. J. “King” Kong
President Merkin Muffley
and, of course, Dr. Strangelove
I’ve thought of some more.
From WKRP in Cincinnati
Les Nessman
Dr. Johnny Fever
Venus Flytrap
From Dan Jenkins’ Semi-Tough
Billy Clyde Puckett
Jim Tom Pinch
And it occurs to me that I appeared in a 3rd grade dental hygiene play as –
Ken Careless
Kel Vartsen and Kosmo Kramer from Seinfeld
The Dark Tower has some nice ones:
Roland Deschain
Mia, Daughter of None
Detta Walker
Alain Johns

I’ve always been partial to The Saint Of Killers from Preacher.

You took my line! 
Raederle, the second most beautiful woman in the Three Portions of An. (actually, any of the character names in Patricia McKillip’s The Riddle-master of Hed trilogy – they all just sound right)
Any of Cordwainer Smith’s names.
Butterflies-are-free Peace Sincere St. Cyr, from eluki bes shahar’s ‘Hellflower’ books.
Oh my God, YES!
My offerings-
Lord Summerisle (The Wicker Man, the REAL one)
Every main character name in Ayn Rand’s Atlas Shrugged and The Fountainhead
Aimee Thanatogenous and Mr. Joyboy (Evelyn Waugh’s The Loved One)
Howard W. Campbell, Jr., the last free American- Heil Hitler. (Vonnegut’s Mother Night)
Montana Wildhack (Vonnegut’s Slaughterhouse Five)
Well then, I may as well mention that I’ve always been amused by the name Bloody Stupid Johnson.
Devastator(!)
