sleaziest group of people I ever encountered was the Yahoo! integration team. I worked at a company acquired by Yahoo! They showed up and handed out documents we "had to sign by end of day". They lost their collective s2t when I said I was going to take it home and have my lawyer look at it.
Them: "You can't come back tomorrow unless you sign it."
Me: "That's fine by me."
Wish I still had filled copy of that doc. It was horrific.
