From 32m 50s, one of the most wonderfully pedantic exchanges I've heard:
Q: Did you send this email Mr. Gates, on or about Aug 8, 1987?
A: I don’t remember sending it.
Q: Do you have any doubt that you sent it?
A: No it appears to be an email I sent.
Q: You recognize that this is a document produced from Microsoft’s files, do you not?
A: No.
Q: You don’t?
A: Well how would I know that?
Q: Well, you see the document production numbers down at the bottom?
A: I have no idea what those numbers are.
Q: Do you recognize this as the form in which email has been printed out by Microsoft?
A: I don’t know what that means. All email printed by anyone looks just like this. So the fact that it looks like this doesn’t give me any clue as to who printed it.
Q: Well, let’s begin with that sir. E-mail printed out by other people are not stamped with Microsoft confidential stamps and Microsoft document production numbers. You would agree with that?
A: That has nothing to do with printing out.
Q: Do you understand my question sir?
A: Nope.
Q: Okay. Do you see down at the bottom where there are “confidential” stamps, and a stamp that says “Attorneys only”, document production stamps? Do you see those?
A: I see the stamps. I can’t characterize whether they’re document production stamps. To me they look more like you’d see on a prisoner’s uniform.
Q: You don’t have any knowledge about these stamps, it is your testimony? You don’t know what they are?
A: I’ve never seen a stamp like that. I’ve never used a stamp like that.
Q: Haven’t you seen stamps like that in every single one of the documents that you’ve been shown during this deposition?
It looks weird, but this is what a well prepared witness is meant to do in a deposition situation: answer only what is asked, if you don't know what is being asked, dig in. If you don't completely recall, then you don't recall.
I don't consider it pedantic in the slightest - the questions were absolutely horrible, and I think Bill Gates was doing his level best to give accurate and honest answers, keeping in mind that he was being deposed, which, is at it's very core, is an adversarial situation.
Look at it another way - which of those question would you have answered differently? Perhaps the only error he made was when he said, "I've never seen a stamp like that" - he should have said, "I don't recall ever having seen a stamp like that."

A: (To counsel) Can you get me all the exhibits?
