How much is Bill Gates' signature worth?

That signature, should I believe that Bill Gates actually signed that. Hell no, what I would pay for is if I saw him in person and he signed it.

That's pretty much what I thought as well.  Actually I probably wouldn't even pay for it anyway; I just don't see any person's signature as being worth that much no matter how well known they are.  Unless it was on a blank check.
