George Robert "Bob" Newhart (born on September 5, 1929) is an American stand-up comedian and actor. Noted for his deadpan and slightly stammering delivery, Newhart came to prominence in the 1960s when his album of comedic monologues The Button-Down Mind of Bob Newhart was a worldwide bestseller and reached number one on the Billboard pop album chart—it remains the 20th best-selling comedy album in history. The follow-up album, The Button-Down Mind Strikes Back! was also a massive success, and the two albums held the Billboard number one and number two spots simultaneously.
