That is actually an interesting argument, that they don't lie about this because if it ever came out they would be in deep shit.

Speaking of which, I had a similarly creepy moment just yesterday. I was watching an episode of the Simpsons, and wanted to Google the Bart blackboard gag in the intro because I didn't get it. Just I type the first word and it immediately suggested the rest. Very creepy because I wasn't watching through any Google service (on an Android phone though).
