Didn't know this, but you can ask Google how tall people are, provided the people in question are famous enough. The results aren't always at the top of the page, either.

Try Thom Yorke and Kanye West:

http://www.google.com/search?q=how+tall+is+thom+yorke

http://www.google.com/search?q=how+tall+is+kanye+west

Now try George Bush:

http://www.google.com/search?q=how+tall+is+George+Bush

No big deal, and I doubt it's anything new, but I thought it was cool. I'm glad Google definitely doesn't know how tall I am. (Why that makes me glad is another story.)

Bush is only pushed down by the Books Onebox,
Any way you only need to start worrying when Google give accurate answers to "How tall am I?"

I can't see anything. It's a Onebox or just text in the results?
