Geek vs Nerd

The most important differences are as follows:

Geek: Thinks Milli Vanilli were pretty cool, scandal or not.
Nerd: Did the spectral analysis on their voices to determine lip-synching well before the press announcement.

Geek: Has 3 friends and trouble meeting new people.
Nerd: Has 3 friends, but recyles through the use of role playing games and secret code names, bringing the total to 27.

Geek: Will be at home come the new millenium.
Nerd: Did the math to figure out the new millenium starts 2001, will be at home for both.
