setup proxy andaccess it through ssh tunnel

Hi,

I would liketo do the following:
install a proxy on my PC at work (running Kubuntu), create a reverse ssh tunnel to my machine at home on port 9999. Then I'd like to access the web from home through the proxy at work, so I assume I would need to configure my machine at home to connect to proxy at 127.0.0.1:9999, am I right here? What exactly is involved in setting up a proxy, I think squid3 is the most common piece of software, right?
Any advice is appreciated!

My advice would be don't do it. People get fired over stunts like this.
