I happened upon
this quiz on the internet. It clearly defines the difference between a "
nerd," a "
geek," and a "
dork," and gives you a quiz to find out where you fit in.
According to their website:
A Nerd is someone who is passionate about learning/being smart/academia.
A Geek is someone who is passionate about some particular area or subject, often an obscure or difficult one.
A Dork is someone who has difficulty with common social expectations/interactions.

I took the quiz, and it declared that I am "
Tri-Lamb Material" because I scored high on both the Nerd and the Dork scales, but not so high on the Geek scale (

My lovely wife took the quiz, and it declared her "
Joe Normal" because she scored low on all three scales.
There's nothing like a good personality test to remind you of the fact that you
married up.
