At one of my first jobs, one of the things I had to agree to was having read "the employee handbook".. but it was not a pdf or other document, it was part of an internal wiki or something, with in-links and out-links all over the place.

I don't recall if I tried to figure out whether the strongly connected component that comprised the handbook was the same as "all pages on the wiki", but I was a little distressed at the time (this being one of my first jobs) that I was being asked to sign my name on something that I couldn't realistically read.
