Before the TV shows, before the blockbuster comedy albums, before he ever told a single joke on stage, Bob Newhart was an accountant in suburban Chicago. It was there that he invented the signature stammering, deadpan delivery that would propel him along a fifty-year odyssey through comedy and our changing times. Newhart recently spoke with WUOT's All Things Considered host Brandon Hollingsworth about the elements of comedy, what he's up to now and why he'll never retire from the stand-up circuit.
