I’ve had two separate passwords make two separate operations puke in the last 24 hours.  The first one was because some of the special characters in one password decided to be the same ones that told the unix perl interpreter at work to go do other things, so it minorly hosed my data conversion.  The second is a different password, and when trying to tell facebook to look through my AIM list and tell me who I don’t have as a friend, it keeps rejecting it, and the only reason I can figure is because of that password.

Security so good, it won’t even let you do what you want.
