<p>The letter isn't too classy, I'll agree with that. But you have to understand that whereas MIT saw it as a prank pulled off on Caltech, Fleming House took it personally. And many of us were actually quite upset. It's the Fleming Cannon, not the Caltech Cannon, like everyone keeps referring to it. And it's considered to be one of those non-prankable symbols of the house, just as the Fleming Bell and the Fleming Flag are. MIT obviously wasn't aware of that.</p>
