While Bob Newhart has been an established name in stand-up in the United States since the 1960s, viewers this side of the Atlantic may know him better from his memorable cameo appearances later in his career in series like The Simpsons - where he was unexpectedly called upon to deliver a eulogy at Krusty the Clown's funeral - and his Emmy-winning role as Sheldon's childhood hero Professor Proton in The Big Bang Theory. Newhart's signature deadpan delivery and slight stammer have been the tools of his trade for over six decades, and this is a great opportunity to discover the rich career of one of the greats.
