Suggestions for Geekout Mix

I'm getting ready to go visit Dunadwarf in a month, and that means several hours cooling my heels in airports, and a two hour car ride from the nearest city big enough to have an airport out to the potato crossroads in the middle of nowhere. So I'm looking for suggestions to load onto my MP3 player and/or burn to CD for the car ride, primarily quirky fun songs. To give you an idea of the type of music I'm looking for, here's the lineup of the Geekout Mix Volume I that I compiled for a road trip this summer:

The Saga Begins
The Dentist Song from Little Shop of Horrors
Sparkly Vampires
Amish Paradise
Ballad of Rufus Amos Adams
Do I Creep You Out?
Grow For Me
Weasel Stomping Day
When a Man Loves a Shark
Ultimate Showdown of Ultimate Destiny
Spiderman (the Weird Al version of Pianoman)
Montage
White and Nerdy
Moonshine
RE: Your Brains
Why Does This Always Happen To Me?

Any suggestions you guys can offer as to similar oddly amusing tunes would be great, especially if you can point me to a place to download a legal MP3 of it.

Yea...Weird Al! He has so many good geeky songs! I remember he has one called "It's All About the Pentiums" which is pretty geeky.

Geeky and Wierd Al... Yoda, obviously

and Cantina Band by Ash is always good for a Star Wars-themed rock out.
