Russell T Davies, producer/writer of Queer as Folk invented a QOF character named Vince Tyler, who is a bleeding heart fan of Doctor Who. This was written before Davies become producer of Who, by the way. In addition, I also recall there is an Otaku no video (anime fanboy) on one of those teen drama shows now. Oh, and Buddy from The Incredibles. Is that all?
The Trio (Warren, Andrew and Jonathan) on Buffy are rabid fanboys of…well, just about anything. Off the top of my head, Star Wars, James Bond and many comics.
EVERYONE in the Buffyverse was a fanboy of Jonathan’s, but only for one episode (Superstar).
There’s some indication in the last season that Xander is a closet fanboy with better social skills.
Curse you, WhyNot, and your rapid posting! I was about to mention the Nerdly Trio and Xander.
Well, fine. Buffy’s an Icecapades fangirl, and Willow used to write Doogie Howser fanfiction.
The Simpsons have Comic Book Guy, (recently named something)
and Bart and Milhouse are rabid fans of Radioactive Man.
On the Drew Carrey show, (the sitcom not Who’s Line) the tall friend was a huge fan of Babylon 5.
Ignatius J. Reilly from A Confederacy of Dunces is a rabid fanboy of Boethius. And wasn’t Miniver Cheevey a rabid fanboy of classical literature? Maybe I’m misremembering; I’m not sure. And Evan Dorkin’s Eltingville Club are pure, distilled fanboy, no question.
Let’s See… still in the Buffyverse, Angel’s a Barry Manilow fan. Charles Gunn is a closet superhero geek, we can infer, as he’s the one that always cracks the superhero-related comments.
Over in Star Trek, Picard has a thing for the Noir genre. Charles Tucker is a classic-cinema fan, particularly scifi/horror.
On Freakazoid, Freakazoid’s pseudo-sidekick was Fanboy.
Everybody in Kevin Smith’s movies is a comics fanboy or fangirl.
Judge Stone on Night Court was a huge Mel Torme fan.

I meant to post this link as a cite:

:smack:
Syndrome from The Incredibles.
When he tosses out lines like:
“I’m still geeking out about it!”
or
“Lame lame lame lame LAME!”
or
“I dunno, that sounds a little dark for you.”
You just know he’s got a box of comix in his closet all bound up and labelled properly. And he has Star Wars (the original release) on Laserdisk from Hong Kong or something.
He’s one of us.
Jay and Silent Bob. Not to mention Brodie.
Jonathan Chance, I don’t mean to offend, but you are posting what sounds like speculation based on dialog. I am all for that when it comes to speculation about thing tat are murely implied. However, there is no need to speculate about Syndrome’s being a fanboy based on the way he talks, as per my OP, Buddy is a fanboy, no speculation needed, and he is the same person as Syndrome. Sorry to be so anal retentive, but I am. Anal retentive, that is. What a :wally I am.
The Lone Gunmen.
There’s Michael (Hal Sparks) from the American Queer as Folk. He’s a superhero fanboy instead of Dr. Who.
Seth Cohen on The O.C. is a big fanboy, and Zach - who dated his ex, Summer, for a while - is one as well.
Dynamite Dan from Grant Morrison’s recent Seven Soldiers #0 is a superhero fanboy, having gained his powers by buying a Golden Age hero’s power rings off eBay.

Both Wally West and Barry Allen were comic book fanboys, paticularly of the Flash, and thus knew what to do when they themselves gained superspeed.
Jeff Anderson.
Lewis.
Jerry Seinfeld was a Superman fanboy. And of of the guys on Stargate SG1 is a Simpsons fanboy.
Eric Foreman on That 70’s Show is a Star Wars fanboy.
And of course, Bart and Lisa both watch Krusty the Clown, but Bart’s the true fan! 
Red Mage from 8-bit theater is an RPG fanboy
