I helped put together a video for Interact that gives a glimpse behind-the-scenes of the Exchange team.
Please don't be scared off by the high production videos and think we're corporate shills - it's just because we got the marketing team to pay for it (score!).
Near the end of the video they have a few shots of various people including myself laughing. I've always wondered what they tell people to make them laugh on camera. So I went in for my interview and at the end, they said "OK we need a shot of you laughing - Joe, tell them your joke" but me being me, I interrupted and said "Oh man, you need a joke to make people laugh, have I got a great one for you."
So I started telling them my joke:
A pirate walks into a bar, with a steering wheel in his pants...
And the entire room erupted in laughter, because apparently that was the exact same joke that Joe had been telling people all day in order to get them to laugh.
So what you see is not me laughing at Joe telling the joke, but me laughing at me telling the joke that happened to be the same joke as Joe's joke. But everyone else, of course, was laughing at Joe's joke.
 Actually, I lie - there are no tacos in this blog post. That is simply the name of a store nearby msft campus that I've always found funny. "Two great tastes that taste great together!"
 I don't know where I first heard it - it may have been from Eric's blog, but I think I first heard it around some Talk Like A Pirate Day. Man, I love that joke.
