I have to confess that I haven't see "Arnie" (I somehow remembered the title being "Here's Arnie!") in 32 years. I wish one of the networks would bring it back for a season. As I recall, it was a very solid show.
Herschel Bernardi was around for years, but I will always think of him as Arnie Nuvo, moved from the loading dock to the executive wing, much to the ire of stuffy old Oglivie. Various episodes still pop into my mind: the time they wanted Arnie to shave his mustache; the time they wanted to impress a youthful executive & wanted Arnie to wear a toupe (and Oglivie to die his gray hair); the time Arnie & his wife went on a second honeymoon; etc. (Please note: I was 8 when the show was on the air!)
I finally saw part of the movie MASH about 2001 and was probably the only person on the face of the earth, who saw Roger Bowen as Henry Blake & exclaimed "Oh my gosh! Hamilton Majors, Jr. is playing Henry Blake!" lol
If you get a chance, watch it; I know I will, if I ever do again!
