Sam installed a IE plugin called Web Viewer today, and when he clicked on the license "agreement," he noticed that it contained this clause:
The Software may contain third party software which requires notices and/or additional terms and conditions. Such required third party software notices and/or additional terms and conditions are made a part of and incorporated by reference into this EULA. By accepting this EULA, you are also accepting the additional terms and conditions, if any, set forth therein.
Get that? When you agree to the EULA for Web Viewer, you also agree to a bunch of other, nonspecified "agreements" somewhere else. Better hope that there's nothin' unreasonable in them!
