Here is a brief list of how to seduce a geek guy:
1- Wear a tee-shirt from XKCD
2- Know what 42 means
3- Tell him you like when you're just the 10 of you.
4- Never admit you use Windows (Mac is OK, Linux is better)
5- When you're about to tell your love, say "sudo love me" (it will never fail)
6- Don't say HTML is a programming language
7- Sing him Saint Seiya's song (even better when in Japanese)
8- Either be a super hot blond or mega ugly female. Inbetween won't captivate their attention.
9- Watch Battle Star Galactica
10- Play WOW or Pong
And seducing a Mac geek is a whole different story. Maybe in another post...
