As a longtime fan of Bob Newhart who has since discovered as an adult the man was even funnier than I'd previously believed, I happily point you to an interesting story by Cathy Seipp in National Review.
Here's a funny bit:
Contrary to Hollywood tradition, the 76-year-old comedian has been famously and happily married for 42 years to the same wife he started out with. When she gets the last laugh on him, he likes to tell the story. “I said, ‘Do you think Joanne Woodward makes Paul Newman take out the recyclables?’” he said, recalling a complaint he made on garbage day. “She said, ‘If you were Paul Newman, I wouldn’t make you take out the recyclables.’”
All this is an especially good thing because Newhart lived with his parents until he was in his late ‘20s and almost never dated. “We didn’t need to dig for dirt to make this interesting,” an A&E producer noted a few years ago, when the cable network’s Biography series premiered Bob Newhart: The Last Sane Man. After a perfectly timed pause, Newhart added then: “Luckily, the bestiality thing never came up.”
The old show is apparently coming out on DVD. I'm priming for a 70's nostalgia moment and may have to pick it up.
