We retired "Bro of the Week" a long time ago (none of you f*ckers read it), but if we still had it, I'd nominate this guy in a heartbeat. 

While on vacation in Australia, 62-year old Paul Marshallsea, from Wales, grabbed a 6-foot long dusky shark by the tail when it came into the surf looking to feast. An Australian TV news team captured the incident, which is the most badass thing I've witnessed since Crocodile Dundee fought off that group of NYC street thugs in "Crocodile Dundee 2."

That's some gangsta shit right there.
