Okay, here are a few I thought up:
1. What are your favorite kind of M&Ms (plain, peanut, peanut butter, etc.)?
2. Hayley: Do you know what the highest note you can sing is?
3. This one's pretty old, but I heard "Pressure" in Simlish today and I had to ask, and I guess it's for Hayley: What was recording Pressure in Simlish, for The Sims 2, like? Also, what did the guys think when they heard it?
4. Do you believe in ghosts? (Does Paramore believe in the paranormal? *rimshot*)
Whoever asked "Who's your favorite Ninja Turtle?"... I second that question.
