who is the vice president of the usa?

Okay, I'll spoil it - MSN returns the (correct) current VP, right at the top, based on their builtin encyclopedia lookup feature.  Google, however, returns some link to Hubert Humphrey as its top link.  Pretty comical actually.  Frankly, I'm not sold on one engine vs the other at this point, but that's pretty lame.
