This is kind of driving me nuts right now, but I seem to recall that there was a very funny Saturday Night Live skit (with Dana Carvey, maybe) about Jerry Brown. I'm guessing that it was during the time that he was Governor of California, so about 30 years ago. Given the fact that he is currently running, I wanted to pin down which episode it was (I think all of the episodes are instantly viewable on Netflix) so I could take a look at it ... I remember that the impersonation was "spot on."
