Anyone remember a hospital show from the `70's or `80's, slightly comedic, where the head Dr. was a short grey-haired guy that looked like Geo. Burns?

I think his first name was, David. He usually wore glasses, sometimes resting on his nose instead of in front of his eyes.
It's not, "Trapper John" or "St. Elsewhere", I already checked.
