Unlike so many other Southern Californian's (not to mention almost everyone that is famous), I've never been lucky enough to meet Mark & Brian but I've listened to their show off and on forever and these guys are something special. This TV show was simply too far ahead of it's time, I watched every episode and I was entertained every second.
I agree with Siskiyous, I think Mark & Brian have woven themselves into the actual fabric of the Socal experience. I've listened to them from day one, I'm listener #12, (yeah I know, so is everybody else, that's the joke), and I've seen few situations where a fan base has come together time and again, to help others or just have a great time.
In an impossible time slot (against 60 Minutes, which was still in it's prime) Mark and Brian entertained me greatly with their adventures. When I watched the show I was not an M&B listener (I have since become one) but what I enjoyed at the time, and continue to enjoy as a listener, is how good natured they are.
