I have him too! Isn’t it badass?
I didn’t think anyone had that any longer. I guess I’ll take mine out of the mylar and use it, then. We had a great Elric-type campaign for about 3 years.
Nerdiest thing? I have the above, and I think the mylar bag helps my case.
I also have all of David Foster Wallace’s books in duplicate, with one copy of each signed with a note. That’s nerdy!

How you doin’? 
You out geeked me, mine is just sitting on a shelf and gets used a few times a year. I still think having the Original D&D Books count for some extra points though I never use them and haven’t since around 1979 or 1980.

I’ve got a Jane Austen action figure. (She comes with her own writing desk and quill pen!)
Depends on which type of nerdiness you prefer.
Computer: A 8-inch floppy disk.
Sports: Dave Magadan action figure.
TV/Movies: Stuffed Rocky, Bullwinkle, Dudley Do-Right, and Snidley Whiplash dolls.
My Starfleet jacket.
DEC Tapes and a programming card from the PDP-11 I used in grad school, and an LGP-21 programmer’s manual. No newfangled 8 inch floppies for me.
A hardbound book edition of the September 1966 Scientific topical issue on computers. It’s actually fascinating how some of the programming techniques demonstarted in a hypothetical checkers-playing program foreshadowed Java of the distant future.
I also have a couple of Time Life Science Series books from the same era. They have become interesting artifacts of their time.
Probably the high-precision tracking force gauge and anti-skating calculator for my turntable. It’s more accurate than the devices that come on the tonearm for making these adjustments. And I use it, too! I have to switch tonearms and settings to play 78 RPM records or LPs/45s, so it comes in real handy.
I still have (and reference, on occasion) my copy of “The Official Preppy Handbook.”
Signed,
Muffy
I recognize that photo. Do you post at FTOTZ?
My husband and I have matching buttons. Mine is Clarke’s law – “Any suffiiciently advanced technology is indistinguishable from magic” – and his is its inverse – “Any sufficiently advanced magic is indistinguishable from technology.”
I’ve ordered Terry Pratchett books that were available only in the UK just because I hadn’t read them.
I own a Blue Sun t-shirt, which I wear frequently. I also paid $30 for a handknit Jayne “cunning hat” for my husband to wear to the premiere of the movie Serenity. He wears it frequently without irony in winter as well.
My husband also owns an adult tricycle in safety yellow. I bow to his superior geekiness.
A nearly-complete set of Star Wars bubblegum cards.
Not one but two BBC Micros (one model B, one Master)
A WhatIfSports.com Simleague Champion T-shirt. I haven’t played real life baseball since I was in high school, but I’ll kick your butt at a statistics-based baseball simulation.
Do you still have Elite on either of them?
What to choose…?
Is it my collection of Comic-Con T-shirts from the last 6 years?
My complete collection of Pratchett British Firsts? Signed?
My catapult wristwatch?
My complete collection of Buffy and Angel trading cards?
Or my autographed picture of Erin Gray (Col. Wilma Deering, Buck Rogers in the 25th Century)? In spandex?
Alas, no. The best I can offer you is Hopper.
For anyone else you didn’t know what one was like me: BBC Micro Link in Wiki
I still have a my first computer a TI99/4a
I have an 8" Floppy from an IBM system 36 Midrange Computer
I have a complete set of The Century Dictionary and Cyclopedia from 1899.
I have recently aquired on this board 7 bound volumes of Popular Mechanics from the 1870’s and 1880’s. Each volume is six months’ worth of issues, bound.
I have a Star Trek Role Playing Manual sign by Walter Koenig when he was filming Star Trek IV the Voyage Home on my Carrier the USS Ranger CV-61.

Wait…it’s sitting (OK, sprawling) right here!
I blew $894 last year on a full 20-volume copy of the OED: http://www.amazon.com/gp/product/0198611862/103-0490643-1455001?v=glance&n=283155
That has to help me somewhat! I proudly identifty as a “Snoot” as well (I wish I could find a t-shirt that proclaims that fact, but I can’t), although my family called it something different (“word snob”).
