Install and run Squidguard in 2 minutes (after downloading ;)).
This page is not yet completed and I should make work of releasing some of these tools.
I made some to simplify the installation process. I made some to facilitate installing some default blacklists for Squidguard. The blacklists in these packages are: You can also use to get these packages automatically (and unattended). When you have to convince people what Squidguard can do, it might be handy to run your existing Squid-logs through Squidguard and create charts of the output. I have a script that actually does that, but I need to rewrite it a bit.

The ouput is a CSV file that contains the source IP address, the blocked destination name, the blocked URL and the original timestamp (and a human readable one).

You can use Gnumeric, Open Office or even Excel to generate some nice charts to show management.
