Funniest. Story. Ever

Ok, so I work in a medical research office (we test on humans, not animals, don't get all upset at me. And the humans are 100% volunteers, they are not paid to be in the study). So, anyway - there was a female doctor that worked here named Katherine, and she came from Austrailia. So one day we are sitting having lunch in the office - this was a while ago - before the election...
Katherine: So, what do you think of the upcoming election?
Me: I think it will be interesting.
Katherine: Don't you think it's kind of weird?
Me: Why?
Katherine: You know - electing Obama?
Me: What do you mean?
Katherine: Well not that long ago they wanted to kill the guy, and now they are electing him president?
Me: People wanted to kill Obama?
Katherine: Um.. yes.. Don't you watch the news (snotty valley girl voice)?
Me: Well ... I read CNN and CBC everyday.. I don't WATCH the news.. but I READ it.. I would think if someone was trying to kill Obama it would be on CNN...
Katherine: It was on there for months - even years...
Me: Really? When?
Katherine: When he flew the planes into the twin towers (in the snottiest voice you can imagine)
Me: Um.. What?
Katherine: Yah, it was kind of a big deal (snotty)
Me: Are you thinking of Osama BinLaden?
Katherine: Yah - the future possible president (rolling her eyes)
Me: Katherine, you understand that Osama BinLaden and Barack Obama aren't the same person right?
Katherine: Silence
Me: Right? Katherine?
Katherine: Silence
Me: Silence
Katherine: Silence
Me: Katherine?
Katherine: Don't tell anyone I thought that ok?
