First Jack gave you the best -- and now, the worst rock star dads...just in time for Father's Day.

BTW, these guys might not really be dads, but something tells us they have kids all over the world.

5. Jimmy Page (When we visit his castle, it's spooky with all the wizard stuff).

4. Dave Mathews (What's that funny smell coming from Dad's office?).

3. Billy Gibbons (Why does Dad want me to grow my beard? I'm only 7 years old!).

2. Mick Marrs (Daddy can hardly walk -- good thing he's so normal).

1. Marilyn Manson (Do we really have to give one reason?).
