On February 11, 1995, Bob Newhart hosted 'Saturday Night Live.' At the time, Newhart was 65 years old. This was Newhart's second turn as an 'SNL' host (the first came in 1980). The 1995 episode was packed with goodness, including a parody of the 'Newhart' skit - where he wakes in bed with Emily and swears that he just dreamed he hosted 'Saturday Night Live.' Trivia: Bob Newhart is current 'SNL' cast member Paul Brittain's uncle.
Actress Ruth Gordon was 80 years old when she hosted 'SNL' on January 22, 1977. Her monologue is pretty good, though not nearly as snappy as Betty White's. She also appeared in several sketches, including 'The Litella Sisters at Home,' where she plays mommy to Gilda Radner's (annoying!) Emily Litella. Major props for that particular episode's musical guest: Chuck Berry.
