That's not at all why we do that.. It's just to find out things about a person if you have no information, so you can find something to talk about.
I'd also find it a bit weird (edit: or awkward) if someone started by asking what I love to do:
Is this a salesman or a recruiter?
Maybe a teacher?
And what should I answer that wouldn't be weird? "Volunteering for Troll patrol at Internet forums"?, "Writing Java"?, "Sleeping"?
Honestly the weirder the better. Its a great icebreaker.
