Very good Rob, for you guys that don't know who "Chopper" Reid is, he's a career criminal and convicted multiple killer, who turned author and is now somewhat of a celebrity, even doing some stand up comedy around Melbourne, where I live.
For some, he's almost a "folk hero", as even though he's a killer, he only killed other criminals apparently. I knew a "crim" a few years ago who spent a lot of time in the same jails as Chopper, and he told me that a lot of the stories in Choppers books were either fabrications, or incidents attributed to other inmates that Chopper "adopted" as his own. Either way, he's a "colorful" character, for sure.
The guy doing the "Chopper" impersonations is a comedian called Ronny Johns, and I think he does a pretty good job. If you want to find out more about Chopper, there's a movie you can see (titled, surprisingly, "Chopper") starring Eric Bana in one of his early roles. Quite a good movie actually, I named my cat "Chopper" in his honor, ha ha! Cheers, Terry.
