RIP Don Knotts July 21, 1924 - February 24, 2006
CNN has his obituary
and they remember him, like most people, as Deputy Barney Fife.This
is his Wikipedia entry for more background.
For me, Don Knotts was one of several people, including Ernie Kovacs, Pat Harrington, Jr., Louis Nye, Bill Dana, Dayton Allen and Tom Poston, who were part of Steve Allen's Tonight Show
that I saw while stationed at remote sites around the world, about five years after it was off the air.
The man on the street
episodes were a hoot as they were barely scripted and heavily dependent on the personalities that each of the comedians developed to interact with "Steverino".
You have to be of an age to react to "Schmock! Schmock!", an in-joke from a long time ago.
