From Newhart's early 90's TV series "Bob" (see my previous entries). I had expected to do more entries on this, but I wan't as impressed with the series as I remembered it.
This episode references the infamous Senate hearings on the comic book industry, which came out of a hysteria generated by psychologist/flim-flam man Dr. Fredric Wertham and his book "Seduction of the Innocent". Comic books were almost made illegal (Wertham was convinced they were destroying America's youth). They were only saved when the comic industry implemented "The Comics Code Authority"--you can hear more about it in Episode 140 of the How I got My Wife to Read Comics podcast. Bob was traumatized by his run in with his version of the Senate hearings--he shows films of the event, with Bob in glasses, a wig and goatee. He has a chance run-in with his accuser who's now an old man yet manages to bamboozle Bob again.
The Complete Series DVD is available on Amazon.
