Just started watching the Extreme Fighting* documentary series on Viewster, and the second episode features Dana's Irish gypsy twin who organizes bareknuckle fights in England...

* Only 2 eps in, but it's the pretty entertaining. In the first episode the crew nearly get whacked arranging a vale tudo fight in Brazil.
