Sometimes, rarely, Eric Zorn is just full of shit.
Yes, public comedy is very specific to time and place, but Laugh-In was very funny perhaps because it did pay attention to the times. I have some retrospective DVDs of the show and while they certainly are dated, they're still funny. And I have fond memories of my family watching it and laughing out loud back in the late 1960s. I'm not denying nostalgia now plays a part in my opinion, but so what?
Oh, and RIP Dick Martin. Thanks for the memories, man.
