[jQuery] Require a specific radio button to be selected - Validation plugin


I have a "terms of use" agreement on my site and I would like to
provide radio buttons with labels of "I Agree" and "I Disagree". If
the user selects "I Disagree" then I'd like a message saying something
like "Sorry, you must agree to the terms and conditions before
proceeding" and if the user selects "Agree" then allow them to
continue.
I can set these fields to be required with the JQuery validation
plugin bit I am at a loss as to how I can require a specific value to
be selected.
Any help will be greatly appreciated.
