The character was played by Tom Poston, and as I grew older, any time I saw him on TV I would stop, watch, and wait for the funny. I watched a lot of crappy sit-com episodes just to watch Poston. He saved his funniest stuff for when he worked with Bob Newhart, and he even fulfilled one of
my
lifelong ambitions by marrying Suzanne Pleshette. Rest in peace, Mr. Poston, and thanks.
