Stolen from my west coast friend Catherine. A couple of these are LiveJournal-specific, but most apply.
COMMENT HERE AND I WILL:
a) Tell you why I friended you. (no such thing as “friending” here)
b) Associate you with something — a fandom, song, color, photo, etc.
c) Tell you something I like about you.
d) Tell you a memory I have of you.
e) Ask you something I’ve wanted to know about you
f) Tell you my favorite userpic from your profile. (only applies to people on LiveJournal)
g) In return, please post this on your own blog.
