What are some interesting questions for an interview?

Well, I have to interview a friend, write about all of it, and then make a speech about it tomorrow. (this was assigned today so don't say that I had plenty of time to do it) The teacher wanted us to use interesting questions, but I can't seem to come up...

with any. So, if you guys have any ideas, that would be wonderful.

Hi,

Ask what kind of shampoo he/she uses
Or how often they floss
Do they have any pets and what are their names?
What would they do with $1 million?
What's the first thing they do when they wake up?
Biggest pet peeve?
Favorite song in the world?
