a. Post a list of 15 fandoms.
b. Have your friends list guess your favourite character AND your least favourite character from each one.
c. When guessed, bold the line, include the character name, and write a sentence about why you like or hate that character.

I don't know if I can come up with 15, but...

1) Star Trek: The Original Series - peachtess got it - Spock
2) Star Wars Movies - peachtess got it - Yoda
3) Farscape
4) The West Wing
5) M*A*S*H
6) Discworld
7) Jim Butcher's Harry Dresden Universe
8) Harry Potter
9) Lord of the Rings
10) Dilbert

That's all I can think of off the top of my head.
Guess away. ;)
