Right, Andrew.
I think I already told this story, but I'll tell it again: When IBM wanted to buy DOS, which Microsoft actually had gotten from Tim Paterson, Bill Gates and Paul Allen went to a meeting with Microsoft's top people to negotiate the sale. Both Gates and Allen were wearing ill-fitting suits, and Allen had a habit of rocking from side to side when he was thinking while Gates had a similar habit except he rocked forward and back. The two of them sat there rocking while the well dressed negotiators looked down on them and negotiations went forward. IBM bought DOS and called it PC-DOS, but Gates talked IBM into allowing Microsoft to sell a parallel version called MS-DOS. As a result of that deal, a few years later Microsoft could have bought IBM with a leveraged buyout.
