You Know Your Husband is a Nerd When:

1. He's excited that he learned a new formula in Excel
2. He used his spare time to make a spread sheet just to use said new formula [f.y.i. "=sumproduct()"]
3. He goes to 3 different websites to get price comparisons for 50+ components for his next DIY project (and puts them in Excel and uses "sumproduct")
4. He has created a folder on his computer for DIY projects and written word documents detailing how to do them
5. His idea of fun is to learn how to solder a circuit board
   
6. He wants to make a head phone amplifier for headphones that he doesn't have
7. He has itinerized all of you possessions in Delicious Library for insurance purposes (and enjoyed doing it)
8. He has been singing a theme song to a Japanese cartoon in his head for 3 days and it hasn't bothered him yet (from Macross Frontier - "Triangler", and I cant speak a work of Japanese, lol)
9. He has organized and renamed all of his photos into more then 260 folders covering the last 7 years
10. He's watched Heroes Season 1&2 twice in less than a year
11. He has scanned all of his photography magazines into text searchable PDF files, and is about to do the same for his wife's magazines
12. He had a small celebration on the inside when he learned the forth coming adaptation of 'The Hobbit' will be spread over two movies, not one
13. More to come...
