Joan and I joked on Saturday about coming to the HUB as a couple of beatniks on open-mike night. That made us think about the demise of Bob Denver, who we remember as Maynard (to most of America he was Gilligan). Don Adams passed away yesterday. The back-to-back deaths of these 60s-comedy icons got me to thinking about how far we’ve travelled since sitting in front of the tube as adolescents. “Get Smart” was a cool, funny show, Agent 99 had sex appeal to spare, and I never felt self-conscious about watching it. It won Emmys, like our favorite drama, “Mission: Impossible.” On the other hand, wasting your time watching a show like Gilligan’s Island” was inexcusable. Mombo would scold us for being glued to the TV set. Shows like Denver’s became known as “glue” in our household, and you couldn’t deny the obvious if stuck in one. There weren’t a lot of choices if you felt like watching television in the 60s, and even after all these years, it’s hard to believe I allowed myself to “glue down” and watch so much junk like that. Now they’re called classics, and people in Hollywood trip over each other remaking them as major motion pictures.
