One of our customers is a school and they installed websense. OMG you should of seen the tickets coming through. Teachers wanted facebook, youtube, hotmail etc... Another of our customers is a hospital, same deal, in fact it got so bad we just scraped the whole web filter project. Nurses were actually complaining to their bosses and escalating it high up because they were pissed that they had "nothing to do at night". It's brutal. Are us IT people the only people who actually do work or what? lol
Though, I think the most painful thing a man can do is get their nuts stuck between the toilet bowl and the toilet seat, while sitting on it.
