I can already see the video, ala the Miller Light "Great taste! Less filling!" ad (I considered posting a direct link, but I'm sure you guys will know how to find it on YouTube):
RP supporter 1: Dr. No.
RP supporter 2: Dr. Know.
RP supporter 1: Dr. No!
RP supporter 2: Dr. Know!
RP supporter 1: Dr. No!!!
RP supporter 2: Dr. Know!!!
RP supporter 1: DR. NO!!!!!
RP supporter 2: DR. KNOW!!!!!
RP supporter 1 shows bills that Dr. Paul has voted NO on, such as the war authorization and the Patriot Act.
RP supporter 2 shows the cover of the Foreign Policy of Freedom book, articles written by Ron Paul, or just a paper with a link to a good YouTube video.
We could even spoof it with our opponents by having their supporters fight amongst themselves. For example, Giuliani's supporters could argue this way:
RG supporter 1: 9!
RG supporter 2: 11!!
RG supporter 1: 9!!!
RG supporter 2: 11!!!!
RG supporter 1: 9!!!!!
RG supporter 2: 11!!!!!!
Hillary Clinton?
HC supporter 1: For the war in Iraq!
HC supporter 2: Against the war in Iraq!
(as they hold up the votes she's cast in favor and against the war in Iraq)
