Yoda vs. Harry Potter...

So during Christmas with my family my oldest son started a debate conversation. Who would win a fight Yoda or Harry Potter and why. Great conversations started with even my youngest son who is 10 contributing. (While playing Lego Star Wars on his DS). So who do you think would win? I will save my decision for my comments.
Then I started these debate conversations:
Who would win a fight Star Trek or Star Wars and why?
Who was more intellegent Gene Rodenberry or Einstein and why?
Okay now your are thinking that my entire family are a bunch of geeks. Not so but sometimes we think like geeks which is not all bad.
Add to my debate conversation list if you have one.
Let the fighting begin, and may the force be with you!
