I liked Karl Malden because I used to watch "Streets" with my eldest sister, in reruns of course because it was never on when I was alive. We're total dorks because we'd notice stuff they did wrong (which was useful in the third grade, San Francisco was the history module) and get excited when we saw houses or buildings from the show. Let's just say we were thrilled when we found out our new step father had worked on the show.
Best episode ever was the one with Arnold Schwarzenegger where he's a body builder and his best line was "I'm not a freak, I'm not a freak for you to laugh at!" and attacks someone. Here's part of that episode
