One of my favorite scenes from Pirates of Silicon Valley is when Steve Ballmer (played by John DiMaggio, yes, the voice of Bender) narrates an audience aside, positively giddy with Ballmer glee at how his clever friend Bill put one over on those stodgy fellows from IBM and got them to give away the golden goose. It was like harpooning the great white whale. While it was a telefilm and thus a fictionalization, near as I can tell things happened pretty much as described.

I have been in similar meetings a couple times, when the client didn't really understand the long-term ramifications of they game plan - and we did. Of course, we weren't as fortunate as Microsoft, but on one instance I remember clearly - and where I made remarks privately as we left the building - the client was more or less forced to acquire, for a unreasoinably high amount, the tiny vendor a couple years down the line.
